Okay, it took me a while to figure out that Christie was a guy - it's an Ireland thing, I guess! It sure made a whole lot more sense thinking of him as a brother! I was thoroughly enjoying the book anyway, but about halfway through, I was again startled by a description or an action, and thought to myself: is Christie a guy? or girl? It was then I read the jacket, where it mentions Christie is a brother - and all was well :)
So Christie's brother Danny is a little, well, odd. Okay, maybe a lot. Sometimes he freaks out and then it's really tough but mostly, he just marches to a different drummer. The drummer is telling Danny it's time to go - find his mother. See, Danny's Dad and Christie's mom got married - so they're kind of half-brothers, or step-brothers or something, but they get along well enough. Well enough to creep out of the house in the middle of the night and start walking down the road. Christie figures he'll talk Danny out of the idea once they hit the bus stop, but well, suddenly, Danny and Christie are on a bus, to get to a ferry, to take a boat, to get to Scotland, to find Danny's mom. It's a wild, wild ride. Did I mention the talking dog?
