Imaginaria: In The Wild: An Artist's Coloring Book of Wonders Inside the Lines

This coloring book is really different from anything else I've seen—all of the main animals are filled with other animals and plants from their habitat. The illustrations are so beautifully drawn and so creative! There's a huge variety of species and plenty of details to play with and add color to. Plus, the paper's nice and thick, so I can even use watercolors. I think this is one of the few books I'll use all the way through (except for maybe the spider one--haha).
