The 5th Wave (The Fifth Wave, #1) - Rick Yancey Five stars isn't enough.

If you only read one book this year, this is the one. It's phenomenal.

The 5th Wave is incredible. An science fiction, apocalyptic story about hope, survival, love and not going down without a fight. Seen through the eyes of female protagonist Cassie, then chapters as seen from Evan, Zombie (a newly recruited soldier) and Sam, Cassie's little brother. Cassie is a brilliant character, she believes she may very well be the last survivor. She carries around Sam's teddy bear as a promise and writes a journal to keep herself sane. She's tough, she's a survivor.

The story is horrific in places and will keep you guessing throughout. It's intelligent, emotional and exhilarating. It's a thriller of epic proportions. I was on the verge of self destruction once I reached slight cliffhanger masquerading as an ending.

I would beg, borrow and steal for a copy of the second book in this brilliant trilogy. I'm so thankful I look a chance on a apocalyptic, science fiction, survivalist novel about aliens, it's truly, hands down, the best book I've read thus far... Ever!
