'Cheshire Crossing,' by Andrew Weir and 'Sarah's Scribbles' creator Sarah Anderson (Ten Speed Press), is a three-way crossover of 'The Wizard of Oz,’ ‘Peter Pan,’ and 'Alice in Wonderland.' Six years after their adventures, a researcher brings Dorothy, Wendy, and Alice together for the first time so he can study them, but they are not down with the program and break out instead. Soon they are careening between worlds, dragging the Wicked Witch of the West, the Jack of Hearts, and Captain Hook with them. (Age 12 up, $14.99)
