Who By Water — Victoria Raschke

Jo Wiley thinks she has everything she needs in her quirky but tidy life in Ljubljana. Her teahouse is thriving. She's surrounded herself with chosen family and her friends, well… several of them come with benefits. When a body is discovered at a glitzy party, Jo's carefully constructed reality starts to unravel. Her lover's murder lifts a veil on a hidden world of ghosts, demons, and forgotten gods where Jo is the link between this reality and the next. She may also be the reason her friends are turning up dead. Jo has to use her new gift to find the killer, and fast, because there are worse things than dying.
