Cass was supposed to be enjoying the final weeks before her eighteenth birthday. Instead, she is killed by a milk tanker and wakes in another world as Cassidy Hart, a young Blood Clan vampire trapped at the level cap of a starter zone. Cass wants sunlight, hot showers, and a future that doesn't end at Monster Level Five. To get them, she risks entering a human city, undergoes a job ceremony no monster was meant to survive, and becomes a hidden Bloodshade Rogue, a Named Roaming Boss, and a vampire who can keep levelling.
There is only one problem. Humans kill unbound monsters on sight.
