Nate Lupo, known as Wolf to those close to him, was a private guy who kept to himself. He didn't get the moniker 'Lone Wolf' for no reason. Being the sniper on his SEAL team suited him well. The only problem was that life was over.

After their last mission-that had gone horribly wrong-Wolf and his team weren't the same. Wolf tried to adjust to life back in the States, but the nightmares and flashbacks wouldn't give him rest.

Nothing helped. Until he met her.

She's sassy, entitled, and rich. His polar opposite. She gets under his skin, and she knows it. Likes it. Fighting back with scowls and grunts of disapproval only spurs her on. Worse yet, everyone loves her. Even his own dog would rather be with her than with him.

But when she realizes her family might be in trouble, she comes to him for help. Despite his strong dislike of her, Wolf jumps at the chance to help. It's what he was born to do. And it gives him the purpose he's been lacking since he returned home.

As he's forced to spend more time with her, he sees the love she has for her three-year-old niece. The way she protects the girl from those who want to hurt her. And the ice around his heart cracks just a little. Maybe she isn't who he thought she was.

When things go from bad to worse and every answer only brings more questions, Wolf calls in his old teammates for help. Without question, they're by his side.

Together, as they separate the truth from the lies, Wolf struggles with what to believe.

What to Believe is the second book in the Sharpe Investigators Series of interconnected standalones featuring a found family, healing, restoration, faith, and clean romantic suspense.
