Timeless - Pandora, #1

Deep within the fortress of Pandora, Lieutenant Vane Schiva has spent millennium guarding precious artifacts and ancient secrets from around the universe. As the son of a decorated commander, he has always been a soldier first, putting the needs of his people before his own desires. So when the compound is breached and he's sent across the galaxies to track down the thief, he never imagined the assignment would lead him to the only thing he's ever wanted for himself.  Growing up in New Orleans, Charlotte Rousseau has seen her share of the strange and unexplainable, but everything she thought she knew about the world is about to be tested.
What started as any other day, quickly spirals into a nightmarish reality, leaving her no choice but to place her trust-and her life-in a stranger's hands. Safety comes at a price, though, and Charlotte soon realizes her only chance at survival means leaving behind her fears and following Vane into the fire.
