The Spy and the Nightingale (Sirens & Spies #1)

Passion sizzles and a lie becomes the truth when a spy and a widow pose as lovers to pursue a dangerous man.

Driven by duty . . .
British spy Nathaniel Blackmore has one objective: find and apprehend an Englishman suspected of treason in France in the tumultuous year after the Napoleonic Wars conclude.
Intrepid Scottish widow Isobel Graham, grieving the loss of her husband at Waterloo, is determined to find her missing younger sister. Her desperate search leads her to Paris on the fringes of Nathaniel’s investigation.

Entangled by choice . . .
Posing as lovers to infiltrate Paris’s most dissolute society, they plunge into ever-widening circles of vice, from an opulent gambling hall to a club catering to debauched desires. In a perilous world of shadows and lies, genuine attraction is a complication.

Compelled by desire . . .
Fueled by danger, their charade as lovers ignites into incendiary passion and something unexpectedly tender – except their relationship isn’t meant to last beyond the mission’s end.
