It's the future and scientists have finally discovered that love isn't a good thing, it's a disease that needs to be cured. So every person on or near their eighteen birthday undergoes the cure for love to prevent them from catching the disease. Lena is just a few months away from her surgery and she's excited to get it, until she falls in love with a young man from the resistance. Now she must decide - continue on with her planned future, or join the resistance, her boyfriend, and her mother's legacy and fight it.
This book was amazing. I loved every minute because there wasn't a dull moment. If I wasn't quickly turning pages to find out how a chase would end, I was quickly turning pages to see how Lena and Alex's romance progressed. Aside from the clever plot, the characters themselves were something to read for. They were deep and had distinct personalities. I was rooting for Lena through to the last page and I even had an affection for Hana who sadly didn't have the courage to resist even though she knew it was the right thing to do. Their friendship was beautiful and it was sad to see it end and even sadder that it would have had to end no matter what Leno chose.
I give Delirium five stars because there is no reason not to. It was a spectacular book to read - now go get yourself a copy!
