Well, I have one book for two days, but it's a book for two voices!! Does that count?
Flickering fireflies, honey bees who want to unionize, a moth's love affair with the porch light and more, Joyful Noise: Poems for Two Voices by Paul Fleischman (illustrated by Eric Beddows) is a phenomenal collection of bug poetry. Vivid images, palpable textures, Fleischman's poems are funny, witty, and full of wonder.
It's the perfect book to read with kids (poems for TWO voices), and it's a great gift for those who simply love words.
