Giant Problem [EPUB ebook] 

Talk about out of the frying pan, into the fire! I was pretty sure that my freaky stepsister and that freaky field guide of hers would ruin my life. But now it looks like they’re going to ruin all of Florida, too! Okay, maybe that’s not fair. Maybe all these stupid giants would be waking up anyway, but if it wasn’t for her and that book, I’d be home playing video games and this would be someone else’s giant problem!
