Little Red Shadow - S. C. Grayson - Bog

The Wolves are out for blood, but Scarlett doesn't intend to let them catch their prey.
When Scarlett's friend Georgette starts receiving death threats from the Wolves, a powerful street gang, she sets out uncover why they want a prominent socialite dead. As a Talented gangster herself, Scarlett goes undercover. Instead of a hardened murderer, she discovers the charming younger son of a Duke, Benedict Pearce, is the would-be assassin. Clearly not a killer at heart, Scarlett decides to trust the handsome rogue, and they join forces to put a stop to the Wolves mysterious machinations and save her friend.
As the pair begin their investigations, as well as a fictitious courtship to throw the Wolves off their trail, Scarlett must reckon with a past she prefers to keep hidden. Benedict, constantly jovial and flirtatious, slowly chips away at the shadows Scarlett has built around her heart.
Still, as the search uncovers deeper levels of deception, their ruse becomes increasingly dangerous. When facing down the Wolves, Scarlett is forced to confront how far into the shadows she is willing to go to protect the ones who have her heart.
