Thank you, basschick, that's a good idea!
Here is a description of the book:
In this unforgettable novel of love, hope, and second chances, a grieving man's personal plan for redemption is suddenly and unexpectedly turned upside down . . . In "If Wishes Were Horses", Wyatt Blaine desperately seeks a reason to continue. Devastated by the senseless deaths of his wife and son at the hands of a drunk driver, he remains unable to forgive, and to love again. Searching for a sense of peace, he decides to revive his late wife's equine therapy program for troubled teens at the Blaine family ranch. By honoring her memory in this way, he hopes to find the sense of closure that has long eluded him. But then Wyatt's pastor asks for the impossible—for Wyatt to meet with Gabby Powers, the widow of the man responsible for Wyatt's unbearable sorrow. Wyatt knows Gabby is not to blame for the tragedy, so when she begs him to accept her troubled teenage son, Trevor, into the program, he reluctantly agrees.
