Legal Tender (Art Series #4)
Andrew Grey

Inside the house Timothy loves so much is a cache of coins with historical value… and a mystery, because one of them isn’t supposed to exist. In memory of his grandfather, Timothy sets out to make sure that the mystery and the coins are given their due honor. In his quest to keep the government from confiscating his grandfather’s legacy, he meets Joiner, whose interest in Timothy is as clear and open as Timothy is guarded. There are things about Timothy's life and his past he doesn't want anyone to know, not even the kind man who is helping him with the complications of legal tender.
