Aria Sinclair thought she had it all figured out. A growing career as a designer, a boyfriend of five years, and a future she was building one careful step at a time. Then Justin dumped her by text. Then she found out he was engaged to her half-sister, Becca. Then she met Roman Black. He was Justin's uncle. A billionaire. Dangerous in ways she could not yet understand. When he offered her a marriage of convenience, Aria said yes. Revenge. Protection. A future. She thought she knew what she was getting into. She was wrong. Because Roman Black is not just a billionaire. He is a man with hidden identities, dangerous enemies, and a past that could destroy them both. And as Aria uncovers the truth about her own family, she realizes her marriage to Roman is not the only secret in her life. Someone erased her memories. Someone lied about her father. Someone is watching. And Roman Black might be the only person who can protect her. If he does not get them both killed first.
