I recommend Partials. 
 ***** 
 It didn't matter that I find Kira flirty at the start. Or I wanted to get rid of Marcus in more ways than one. Or I wanted Jayden's character to be realized in its full potential. Because Partials took all my attention and focused it on its fantastic plot and its solid execution. It felt good to read a post-apocalyptic book that doesn't delve on romance alone. This is one smart, action-packed story, you guys. 
 Sixteen-year-old Kira doesn't believe in the Hope Act anymore (eighteen-year-old girls are mandated by the government to get pregnant in two months to grow the numbers of humans). When the Senate lowered the age to sixteen, Kira decided to pursue her idea, no matter how far-fetched, that perhaps Partials holds the key in the RM cure (infants die days after being born because of the RM virus). Why? Because she doesn't want to pregnant at such a young age. Because she cannot stand watching all those babies die. Because she doesn't want to live that kind of life. Everything changed when they encountered a Partial. 
 There are elements that are predictable but still I was surprised when those predictions happened. To say that a plot-driven book gave me enjoyment despite little connections with the main characters is a first for me. Kira's okay but I love Xochi more. Marcus is a clown and a whiner at the same time. Jayden, I so love. Until the end, he was my favorite character together with Samm. And Samm is unbelievable. His actions and thoughts are true to his character. Although his exposure is short-lived, I want to see more of him in the sequel. 
 There are times I get lost to all the genetic talk but that's fine. I just flip back a few pages to understand it more. And i thought this book is too long. But Well's writing is very engaging. Every chapter end made me want to start the next chapter immediately. 
 So what else can I say? Partials is really good. Never mind those characters that I didn't like. Because Kira's story will absorb you 'til you get to the very end. And because of this, I am wildly anticipating its sequel, Fragments.
