Protect Thy Enemy by Marilyn Don

For lovers of Ana Huang’s Twisted Games and Catherine Cowles’ Hidden Waters, this slow-burn romance crackles with tension and suspense.

Arden Williams has spent her whole life proving she belongs. First at the academy, now as a rookie agent in the Secret Service. But when she’s assigned to Holden Grant, the cold and ruthless agent known for breaking recruits, she realizes her biggest challenge isn’t the job–it’s surviving him.
Holden Grant doesn’t do distractions. Especially not ones with sharp eyes and sharper tongues. He’s there to train her, not get tangled in the past she doesn’t even know she’s carrying. But Arden is a walking reminder of the ghosts he can’t escape and the promise he never should have made.
Tension turns to fire. Fire turns to something neither of them are ready for.
Because in a world where loyalty is everything, falling for the enemy is the most dangerous move of all.

Packed with enemies-to-lovers tension, forced proximity, and forbidden romance, Protect Thy Enemy is a heart-racing start to the Desire & Duties Duet.
