The only shifter available was a B-rank snake no one wanted—Silas. He came with his twin brother, River. Wren took them both. She didn't know Silas was the one who'd saved her that day. he'd hidden his SSS-rank just so she'd pick him. Now her ex is begging at her door while Silas cooks her dinner and River warms her bed. Then the Bonding Agency calls: Silas has been reassessed. A better match is available. His answer? " "I choose Wren."
