Life was “ova” for hard-boiled hardman Humpty Dumpty. Shattered after a free-soloing fall at his home crag, Dumpty lived a life of seclusion, TV watching, and potato-chip snarfing . . . until one day, he had to rescue the king’s favorite horse from a cliffside. Perfect for young climbers (and even old ones), Humpty Dumpty Climbs Again ($16.99, penguin.com/youngreaders) adds a vertical twist to the classic nursery rhyme. Author Dave Horowitz, a climber and former Eastern Mountain Sports guide, describes the book as an “eggsistential tale of hope and redemption.” Delightfully illustrated, with clever literary and climbing allusions, the book follows Mr. Dumpty’s triumphant return to the heights.
