“I guess that’s just part of loving people: You have to give things up. Sometimes you even have to give them up.”

― Lauren Oliver, Delirium

Lauren Oliver's dystopian young adult romance book, Delirium, was released by HarperCollins in 2011 under the HarperTeen imprint.  The narrative centers on Lena Haloway, a young lady who falls in love in a culture that views love as a sickness.

Synopsis from Goodreads...

In an alternate United States, love has been declared a dangerous disease, and the government forces everyone who reaches eighteen to have a procedure called the Cure. Living with her aunt, uncle, and cousins in Portland, Maine, Lena Haloway is very much looking forward to being cured and living a safe, predictable life. She watched love destroy her mother and isn't about to make the same mistake.

But with ninety-five days left until her treatment, Lena meets enigmatic Alex, a boy from the "Wilds" who lives under the government's radar. What will happen if they do the unthinkable and fall in love?

My reaction to this novel...

When I first picked up Delirium, I was so excited. The idea instantly caught my attention, a world where love is considered a dangerous disease, something that must be “cured” before you turn eighteen. The government controls everything, and people live without the risk of heartbreak, passion, or even deep connections. It sounded unique, a fresh twist in the dystopian genre, and I couldn’t wait to dive into this world and experience the intensity I imagined would come with such a premise.

But as I started reading, I realized this book moves much slower than I expected. The beginning takes its time introducing Lena, the main character, and the society she lives in. Lena actually believes the government’s rule that love is harmful, and she’s counting down the days to her procedure, the cure that will make her immune to this so-called disease. The first part of the book focuses heavily on her daily life, her past, and her fears. While I appreciated getting to know her, I found myself wishing the story would pick up pace and throw me into some tension or action sooner.

The writing style is beautiful, I won’t deny that. Lauren Oliver’s prose is almost poetic at times, and she paints vivid pictures of the setting and emotions. However, this beautiful writing also adds to the slowness. There are pages and pages describing scenes, memories, and feelings, which can be enjoyable if you love that kind of descriptive style. For me, though, it sometimes made the story feel like it was dragging. I wanted more movement, more suspense, and more moments where I couldn’t wait to turn the page.

As for Lena, she starts off as a very cautious and obedient character. She trusts the system she grew up in, and it takes a long time for her to question it. Her transformation does happen, and it’s believable, but it’s a slow journey. Meeting Alex, a boy who has not been “cured,” is what begins to shift her perspective. Their romance is gentle and gradual, and while it’s sweet, it didn’t hit me with the emotional punch I was hoping for in a story where love is forbidden and dangerous. I wanted to feel the risk, the passion, and the urgency of their relationship, but it felt more calm than intense.

One thing I did enjoy was the world-building. The idea of outlawing love and labeling it as a disease is fascinating. I liked the little details the author included, such as government-approved sayings, propaganda, and the way society was structured after the cure. It felt believable in a chilling way. However, sometimes the focus on world detail took attention away from the actual plot, which made the pacing even slower.

The last few chapters were the part that really drew me in. Finally, there was more action, more tension, and more emotion. It felt like the stakes were higher, and I was eager to see what would happen. But by that point, I had already spent most of the book waiting for something big to happen, and it came too late for me to feel completely satisfied. The ending is a cliffhanger, and while it sets up the next book in the series, I wasn’t sure I wanted to continue right away because I didn’t feel fully hooked from the start.

Overall, Delirium is an interesting book with a unique concept and beautiful writing. I can see why some readers would fall in love with it, especially those who enjoy slower-paced stories with lots of detail and a gradual build-up. But for me, it felt too slow. I wanted more heart-pounding moments, more urgency, and a romance that made me hold my breath. While I don’t regret reading it, it wasn’t the gripping, fast-paced dystopian I thought it would be.

For my personal experience, it has potential, and the premise is amazing, but the pacing made it hard for me to stay fully engaged. If you’re a patient reader who loves poetic writing and slow-burn stories, you might love it more than I did. But if you’re looking for a book that grabs you right from the first chapter and doesn’t let go, this might feel like a long wait for the payoff.

My Overall Rating: ⭐⭐✨(2.5/5)

Have you ever had a crush on a fictional character? Stayed up until 2 a.m. whispering “just one more chapter”? Felt your heart race during a plot twist? Yeah, me too.

Reading is so much more than just flipping pages. It’s a full-body experience. It’s crying in your blanket at 1 a.m., it’s blushing alone in a coffee shop, it’s screaming into your pillow because something in a book felt too real. In a world that moves too fast and expects too much, books are that one safe space where we can pause, feel, and be free.

Let’s talk about the joy of reading, why it feels like falling in love, and how books lowkey saved our emotional lives.

Reading Isn’t Boring — You Just Haven’t Found The One

Raise your hand if you’ve ever been told, “You just need to read more classics.”

Now raise your other hand if the last classic you read almost put you to sleep.

Here’s the truth: reading isn’t boring. What’s boring is being forced to read something that doesn’t feel like you. The secret to falling in love with books is finding one that feels like a mirror — or a window — or even a wild escape tunnel.

You don’t need to start with Shakespeare. Start with:

                    🌸That Wattpad story you secretly loved in high school.
                    🌸A cheesy romance that makes you giggle.
                    🌸A coming-of-age novel that reminds you of you.

Once you find that book — the one that feels like it was written just for you — there’s no going back.

Reading = Feeling Things You Didn’t Know You Needed to Feel

Books are emotional therapy, and here’s why:

                    🌸A character’s grief can help you grieve something you haven’t talked about.
                    🌸A plot twist can remind you that life isn’t always predictable — but it can still be beautiful. 
                    🌸A happy ending gives hope when yours feels far away.

Reading is emotional self-care. It’s letting yourself cry without having to explain it. It’s remembering your worth when you forgot it. It’s traveling to places you’ve never been while wearing your ugliest pyjamas.

Sometimes, life is too loud to read. And that’s okay. Books will always wait for you. They don’t judge if you stop midway. They don’t mind if you forget the plot. They don’t guilt-trip you if you return after months.

Books are like best friends who sit quietly beside you until you’re ready to talk again.

Maybe life has been messy lately. Maybe your mind is too tired. Maybe your heart’s a little heavy. But maybe, just maybe… the right book is waiting for you.

So take that book off the shelf. Open to page one. And fall in love again. Because sometimes, the softest kind of healing comes from the quietest kind of love — the kind you find between the pages of a really good book.
