At the Bottom of Everything by Ben Dolnick

A very well written novel, At the Bottom of Everything is the first book by this author that I have read. In the beginning it looks like a story about a junior high/high school friendship, Adam & Tom, kids that became very close. Adam comes from a broken home, has a new stepdad. Tom comes from intellectual parents, just the sort that Adam relishes. So Adam starts spending all his time at the Pells' with Tom, two peas in a pod, more like brothers. Basically two good teenage boys, learning about girls, getting into very little mischief. Adam is the more social of the two and when he gets into sports and starts hanging with different kids, the friendship starts to fade.
One night trying to recapture the friendship, the two are involved in an accident that will change their lives forever. A guilty secret that they keep, decides which way these two lives will move forward, on separate paths.
Tom Pell heads into a spiral of mental illness, Adam Sanecki's life just never gets on track. A chance meeting with Pell's parents sets Adam on a journey to India in a search for his lost  friend. 
A very intricate tale is woven by author Dolnick. Is it guilt from the secret that has directed these two lives, the lives of Pell's parents, as well? What a person will go through to keep another from revealing a devastating secret..is this the motive for Adam? The last few chapters of this book are fast paced and written so that the reader can feel the panic build...and you do. At the Bottom of Everything..good read.
