Funeral Singer: A Song for Marielle - Funeral Singer, #1

As a spirit escort, Gillian helps unsettled and confused souls to cross to the higher realm. But when a murdered girl refuses to go, can a mere mortal help her resolve her issue? As a musician, Gillian finds moderate recognition in her hometown. Still, she wants enough success  to quit her day job that barely pays the rent. Following a singing gig, she falls and hits her head. Shortly after, she begins to develop an extrasensory skill that leads her down an unexpected path.
She becomes a spirit escort, a human assigned to assist the newly departed souls to find their way to the next level. Sometimes the souls have one last request, and they want Gillian's help. Then she encounters a client who is unwilling to proceed. The young girl declares she won't cross until Gillian finds the man who murdered her and brings him to his punishment. Are her new skills enough to help Gillian succeed, or will they place her in mortal danger?
