The Accidental World by K.A. Griffin | Review-Interview-Giveaway
If my return is delayed, then you are in danger. Set your plan into motion. Appropriate dress is required. Ethan Scott lives with his grandfather above Bingham's Rare Artifacts, an unusual store with even more unusual customers. He's a whiz at a board game only he and his grandfather seem to have heard of. And rather than friends, he surrounds himself with the trappings of an unknown past. Until his grandfather goes missing, leaving behind a cryptic letter, a valuable gift, and a very confused grandson. To save him, Ethan must conquer time and space and embrace an unlikely destiny. But as he plays the part that seems to have been written for him, Ethan is swept up in his grandfather's secret but not-so-distant past . . . and discovers that his own future is wrapped up in it.
