In My Soul to Take, Thóra is representing a client intent on building a wellness spa. The client believes the land he's purchased is haunted and that the people who sold him the property hid that fact in order to sell. Ghosts could be bad for R&R, and he wants Thóra to prove the sale was under false pretenses so that he can at least get some of his purchase price refunded. But when a body is discovered nearby, Thóra finds herself thrust into a murder investigation with her client the prime suspect.

This was an especially fun entry in the series as it includes both Icelandic folklore and more of the dark history of country. The mystery wasn't quite as tightly plotted as Last Rituals, but the character development makes up for that quite a bit. Thóra's relationship with Matthew and her troubles with her children get a lot of attention in this outing. Sigurdardóttir also injects quite a bit of humor into this installment (and subsequent ones).
