Sadie Hoagland and Maria Kuznetsova first met in 2008, when they were studying fiction writing at UC Davis under Yiyun Li, Lucy Corin, Lynn Freed, and Pam Houston. Each has a second book out this spring — Kuznetsova’s second novel, Something Unbelievable, from Random House, and Hoagland’s debut novel, Strange Children, from Red Hen Press — so they took this opportunity to catch up.
