Double Trouble in Walla Walla [PDF ebook] 

It was an ordinary Monday morning in Walla Walla-until Lulu walked up to her English teacher’s desk. "Mrs. Bell, I feel like a nit-wit. My homework is all higgledy-piggledy. Last night it was in tip-top shape, but now it’s a big mish-mash." With those few words, things become not so ordinary after all, for it seems that Lulu has opened up a super-duper, helter-skelter WORD WARP. Luckily for Lulu and the rest of the English-speaking world, the school nurse has an idea about how to handle this hodge-podge of topsy-turvy chit-chat. Will it work? Zig-zag through the jibber-jabber and the yakety-yak to find out!
