I received this book as a FirstRead in exchange for my unbiased opinion. 
 Eva Walker has an unusual "gift". When she touches people or even objects that belong to them, she feels the emotions and major incidents of their lives. Eva has learned to stop touching people because she can't do anything to help with what she learns, except to hold the calculators of the people she tutors. When Eva meets Zenn Bennett, though, she wonders if he would be worth the risk. 
 I loved this book! I read it through in one night; I couldn't put it down. As someone with a degree in math, I loved the math nerd side of Eva. The story handles some serious topics but without getting too depressing.
