The Alpha Books in Order

The Alpha series is an adult contemporary romance sequence built around Stella Mulroney and Gabriel, or Gabe, Gregory. The title refers to Gabe's commanding personality, but the series is also a suspense story about revenge, family secrets, and what happens when two people investigate powerful men connected to their own painful pasts.

The Alphabet Game begins when Stella finally gets an interview at Gregory & Sons, a leading London law firm that handles her wealthy stepfather's interests. She has spent two years trying to get close enough to discover what her stepfather is really involved in. Her plan is not about career ambition. She wants evidence that will help bring him down.

Gabe notices her immediately.

Gabe is the son of the firm's senior figure, and he has his own reasons to question the men around them. He is drawn to Stella's anger and proposes a private alphabet game that adds heat to their growing partnership. While the sexual game gives the series its title and adult-romance focus, the larger plot involves investigation, danger, and secrets that neither character fully understands at first.

The early story follows Stella and Gabe as attraction complicates their work. They are trying to expose wrongdoing while learning that their own families may be more deeply connected than expected. Their relationship is intense, sometimes playful, and often shaped by the question of whether either can trust the other.

The related books, including The Alphabet Wedding, The Calendar Game, and The Baby Game, continue the characters' story beyond the initial investigation. The sequence is best read in order because the emotional and family developments build from the first book's revelations.

Start with The Alphabet Game. It establishes Stella's reason for seeking revenge, Gabe's role in the danger surrounding her, and the blend of erotic romance and suspense that sets this series apart from Long's lighter rom-coms. Expect a London setting, powerful families, adult content, hidden motives, and a central couple forced to decide whether desire can survive the truth.
