Got this free, thinking it might add some variety to my usual diet of mystery and history. But I couldn't put it down! I'm a hiker, not a climber, but the climbing adventures were explained well enough to understand without dumbing down the readability. In fact, that's what drew my attention to the book in the first place. But along the way, I also grew interested in Patrick and his dad... feeling their pain and uncertainty, and grasping at the slight tendrils of hope they discover. Their story was surprisingly (and thankfully) a bit unpredictable, and as another reader commented, it sounded more like a memoir than a novel (a good thing, in this case). It was realistic in its intermingling of disappointment and lost hope, with achievement and faith and renewed hope. In fact, this overall theme of the book is portrayed in one of the very last sentences: Sometimes, hope is all you have.
