Adventurers Wanted: Slathbog's Gold by M.L. Foreman

When 15 year old Alex sees a sign in the window of a cluttered bookshop advertising for adventurers to apply within, he doesn't think much of it until he looks away, looks back, and the sign has changed! Wanting to find out what sort of mechanism changes the sign, he goes inside to ask the shop owner about it. Before he knows it, he's whisked off on an unexpected adventure, making friends with elves, dwarves, and others, and on his way to battle a dragon who's been terrorizing the countryside! While I found the story a bit predictable, and the characters somewhat one-dimentional, it is overall an enjoyable story that middle grade to YA readers would enjoy. Slathbog's Gold by M.L. Foreman was first published in 2009.
