The Flying Troutmans by Miriam Toews
Meet the Troutmans. Hattie is living in Paris, city of romance, but has just been dumped by her boyfriend. Min, her sister back in Canada, is going through a particularly dark period. And Min's two kids, Logan and Thebes, are not talking and talking way too much, respectively. When Hattie receives a phone call from eleven-year-old Thebes, begging her to return to Canada, she arrives home to find Min on her way to a psychiatric ward, and becomes responsible for her niece and nephew. Realising that she is way out of her league, Hattie hatches a plan to find the kids' long-lost father. With only the most tenuous lead to go on, she piles Logan and Thebes into the family van, and they head south . . .
