Aurora

"When 32-year-old Elena Ricci wakes up in the hospital, the last thing she recalls is walking home from work the night before. Except the night before turns out to be eight years ago and Elena has no memory of the time she's lost. Family feuds, breakups, and sexual awakenings--all forgotten. For Keelin Jax, Elena's wife, the long nightmare only continues upon Elena's awakening when Keelin becomes a platonic roommate overnight. While Elena struggles to adjust to her new present and find the life she left behind, someone from Elena's past finds a way to seize the opportunity after years of silence."--Amazon.com
