Raven Dexter, Paranormal Midwife (Nexus Chronicles, #5)

Raven was off to a good start as a midwife until an elf demanded she attend a royal goblin's birth. It was downhill from there.

Raven Dexter chose to pursue midwifery the moment she helped a teen friend deliver her baby. Fed up with unconcerned physicians, she studied until she could open her small practice in a moderately sized town. Her practice was slowly growing until the night a strange man demanded he come with her to attend a birth. Her introduction to the paranormal society was in the venue of delivering a small goblin baby that quickly took a chunk out of her arm.
The elf that took her to her first delivery moves in without even asking, taking care of everything from her appointments to making her meals, Eyleno Mik rapidly becomes indispensable and then becomes something more.
