by Leif Enger.
Quickie recap: Reuband Land shouldn't be alive, but his father's miracle saved him from stillbirth, and he has been witnessing the man's miracles ever since. His family launches upon an adventure to find their fugitive brother and the results are nothing short of miraculous.
Quickie review: Normally I would be wary of such a premise, but this book manages to be unassuming and yet addictive at the same time. The characters are created with such restraint that even considering the topic at hand, they're always approachable and extremely readable.
Quickie recommendation: I couldn't put this book down, and that's the highest praise I know how to give.
