Perfect for you if...

You love military romance where the action sequences matter as much as the chemistry between leads.
You're drawn to smart heroines who can match their heroes intellectually, not just physically.
You want high-stakes danger balanced with genuine emotional stakes and steamy tension.

Maybe not for you if...

You prefer slow-burn romance without explicit content.
You're sceptical of the 'fake relationship to real feelings' trope and need more originality in your meet-cute.
You want standalone novels rather than series openers that leave you needing book two.

About this book

Navy SEAL leader Ryan "Con" Constantine is tasked with faking a marriage to Sophie Edwards, a cryptologist, in order to stop a terrorist plot. Sophie excels at solving puzzles, but pretending to be Con's wife presents an unexpected challenge. As their mission progresses, the line between their fake relationship and genuine feelings becomes increasingly blurred. With the clock running down and stakes rising, Con must protect Sophie while she becomes determined to save him. Operation Heartbeat is the first book in the SEAL Team Blackout Charlie series, combining military suspense with romance.
