Wild Hope by Joan Thomas

A CBC Books and Winnipeg Free Press Best Book of the Year
From the Governor General's Award–­winning author of Five Wives, a thrilling contemporary novel about how the past never lets us go
Isla and Jake are a couple drifting apart. She is a chef and co-owner of a farm-to-table restaurant on the brink of closing; he is a visual artist tormented by the oil-and-gas legacy of his late father. A looming figure in both their lives is Reg Bevaqua, Jake's childhood friend-turned-enemy, turned bottled-water baron.
Reg is a demanding regular at Isla's restaurant and a man with a seething resentment toward Jake. With good reason, the feeling is mutual, but Jake keeps their past from Isla as he follows a devastating trail to the source of Reg's wealth. When Jake disappears following a winter camping trip, Isla starts to connect the dots, with all roads leading to Reg and his magnificent property on Georgian Bay.
Seamlessly weaving together observations on the entitlements of the wealthy, the monetization of water and the politics of art, Joan Thomas has created a layered, page-turning read about how far we will go to hold on to power and what we will do to avenge old wounds.
