Harlequin will publish Rachel Reid‘s next Game Changers novel, UNRIVALED, the seventh in the series, on September 29. The romance series was adapted this year into a popular TV show by Crave and HBO. Deadline writes, “Unrivaled serves as a direct sequel to the previous book The Long Game, which follows Ilya and Shane a decade into their relationship. Fans watched them fall in love during the first season of Tierney’s TV adaptation, which was based on the second book in the series, Heated Rivalry.”
