Brink of Life by Rick Moskovitz
A woman plunges into consciousness in the midst of what seems like someone else’s life, sending her on a quest to discover who she is and to craft an identity that makes sense within her current circumstances. As she digs into the mystery of her life, she uncovers a top-secret government organization plotting world domination and a clandestine vigilante organization dedicated to destroying it and is caught between these warring factions. Nobody in her new world is exactly who they appear to be, including herself. Identity, she learns, is complicated and inseparable from the body in which it resides.
