The Relentless Hero by Angel Vane

Mena Nix has everything she ever wanted—a prestigious job and Julian Montgomery, the love of her life by her side. But secrets from her past could destroy the new life she’s built for herself.
Julian Montgomery has a chance to rekindle his career as a special operative for a private security firm. He craves the action but turns it down to protect his relationship with Mena.
But Julian is thrust back into the world of special ops when terrorists attack the museum where Mena works. Bodies are piling up and Mena’s nowhere to be found.
When Julian discovers that Mena has been kidnapped by one of the most ruthless criminals in Africa, he vows to find her or die trying.
Can he outwit the diabolical mercenary and rescue the woman he loves before it’s too late? Or will the secrets Mena has been harboring cost them their lives?
