Billion Dollar Baby by Aiden Bates

Getting attached was the cardinal sin…

As an omega FBI agent, Giovanni Rizzi has done more undercover operations than are good for him. He’s on his third op in two years and having trouble remembering who he’s supposed to be. When a one-night-stand ends up being his new boss, the mission gets messy.
Alpha Marcus Stern’s new FBI job isn’t everything he expected it to be, his authority hampered at every turn. If the boredom doesn’t kill him, the loneliness just might. Especially since the hot one-nighter he can’t forget turns out to work in his department. If only he could shake the nagging feeling that he’s missing something…

Gio’s investigation and Marcus’ digging collide. The men can’t deny the draw between them – but the ethics of their relationship is the definition of complicated. When an unexpected pregnancy and a break in the case send the men scrambling, will they be able to overcome all the secrets between them, or will their relationship go down in a hail of bullets?
