Universe Hunter — C.L. Scholey

Being lost in the forest is the least of Cali's worries when she's attacked by flesh-eating creature not of this world. She is rescued by a scorching alien light that kills the creature but inadvertently burns her. Cali wakes to find her body healed but her sanity in question. She can't really be zipping through space on a vessel manned by two light beings who have taken the form of human men -- two sexy as hell human men calling themselves…Universe Hunters.

Two male beings, one human female. Life as Cali knows it changes in the blink of an eye, or in her case, a flicker of light.
