Covert Mission by Rebecca Deel

Brutally attacked and left for dead was not the way second-generation cop Seth Dixon wanted to start his day. When he’s set up for the murder of his confidential informant, Seth figures his chances of scoring a date with his beautiful running partner are slim to none.
After discovering the murder is connected to a deadly militia brewing big plans, the Feds ask Seth to infiltrate the group. His partner is none other than the woman who stars in his dreams, the mysterious Teagan.
Tasked with unraveling a conspiracy leading to the nation’s capital, Seth plays a deadly game of cat and mouse with men who will stop at nothing to achieve their goals. Protecting Teagan and preventing an assassination become the most important missions of his life. Failure will be fatal.
Fortress Security operative Teagan Paloni thought she left the past behind, but some shadows refuse to stay buried. After spending years rebuilding her life, she plunges into the depths of her worst nightmare to protect the man she loves. With the stakes higher than ever, Teagan must defeat her demons and foil a plot to throw the country into chaos. One misstep, and Teagan will lose everything, including the man with whom she longs to build a life.
