Puns, Allusions, and Other Word Secrets by Jennifer Fandel

This book is part of a great new series called Understanding Poetry, and it's the best book I've seen for older kids about poetic devices. The poems that are used as examples are by some of my favorite poets: Pablo Neruda, e. e. cummings, Dylan Thomas, and William Carlos Williams, to name a few. Each book in the series tackles a different set of devices, and with the wonderful examples given it's really easy to see what they're all about.
