Eleven-year-old Peter Lee has one goal in life: to become a paleontologist. But in one summer, that all falls apart. Told in short, accessible journal entries and combining the humor of Timmy Failure with the poignant family dynamics of Lynda Mullaly Hunt, Peter Lee will win readers' hearts. Eleven year-old Peter Lee has one goal in life: to become a paleontologist. Okay, maybe two: to get his genius kid-sister, L.B., to leave him alone. But his summer falls apart when his real-life dinosaur expedition turns out to be a bust, and he watches his dreams go up in a cloud of asthma-inducing dust.      Even worse, his grandmother, Hammy, is sick, and no one will talk to Peter or L.B. about it. Perhaps his days as a scientist aren't quite behind him yet. Armed with notebooks and pens, Peter puts his observation and experimental skills to the test to see what he can do for Hammy. If only he can get his sister to be quiet for once -- he needs time to sketch out a plan.
