Last Hour till Sunrise by Lisa Phillips

The fight never stopped.

All DEA Special Agent Lucia DeSoto has is the job. Until a routine operation goes wrong and she’s captured by the target. The one person who can save her is a man she swore she would never see again.
Andre Martinez is only good at being a soldier, so when he hears that Lucia was captured and the feds aren’t mounting a rescue he goes after her. But it doesn’t mean they’re getting back together.
When a deadly enemy comes after them, Andre and Lucia must combine forces. The team of Chevalier Protection Services bands together to protect their own, but will it be enough?
Cut off and pushed to their limits will they outlive the Last Hour Till Sunrise?
