If You Find This

His father has lost his job, and they'll have to sell their house, which holds the only memory Nicholas has of his younger brother. Just in time, Nicholas's ancient grandfather arrives, filled with tales of priceless treasure he has hidden in town--but where? With the help of misfit classmates, two grandfathers, a ghosthouse, hidden messages, seances, and an uncanny mind for numbers, Nicholas stages a nursing home breakout, tangles with high schoolers in smugglers tunnels, and gets swept up in a duel with the biggest bullies in the neighborhood. Will it be enough to find the treasure and save his house?
