Heirs' Games

Forty-six billion dollars. This fortune was bequeathed before his death by billionaire Tobias Hawthorne to seventeen-year-old Avery. The girl never knew about the existence of the old man, who loved riddles, anagrams, and all sorts of quests. To receive her share of the inheritance, Avery must play a risky game devised by the eccentric rich man. But his heirs are willing to do anything to prevent their rival from obtaining the huge fortune.
