The Revised Fundamentals of Caregiving is a sad but not humorless look at a man who has lost everything that matters, as he stumbles toward something like hope, or at the least the possibility of maybe having hope at some not-too-distant future time. 
 Ben is a total wreck when he takes a job caring for Trevor, a 19-year-old boy severely disabled by progressively degenerating muscular dystrophy. Ben doesn't know how to do much of anything besides provide care, having worked odd jobs and been a stay-at-home dad in his earlier life. Finally out of any means of supporting himself, Ben becomes a certified caregiver, and by caring for Trevor, takes baby steps toward his own long-overdue healing. 
 I found this book touching but not heavy-handed, and the voice throughout is leavened by humor, despite the truly horrible disaster in Ben's past. An odd assortment of quirky characters come in and out of the storyline, most neatly defined although not necessarily believable (Trevor's estranged father is so incessantly accident-prone that one wonders how he's still alive and functioning), and, oh yes, there is a road trip. I myself am not a fan of road trips, whether in books or movies (although I don't mind them in real life), but the journey of Ben and Trevor is a fairly effective plot device, and is a mostly effective metaphor for Ben's own journey through grief toward healing. 
 Overall, I enjoyed this book and have no hesitation about recommending it.
