When Abby and Ophelia learn that a young girl has disappeared in PSI, a remote Minnesota commune of psychics, the pair of witches take a vacation to see if they can help locate her. They are quickly joined by Ophelia's friend and employee, Darci, who loves an adventure as much as anyone.

What they discover is a small town with more secrets than just PSI, including a lakeside resident with a hit and run driving record, a Native American veteran with a justifiable anger at white people, and a whole lot of shamanistic talent.

What breaks the trio's heart though is learning of another young girl, silver haired and lavender eyed Tink, who has strong talents as a medium and is being drugged and spelled to keep her talents in check.

The trio are in a desperate race to solve the mystery of what PSI is about so they can save both missing girls -- and ultimately themselves. "Trouble" is moving away from the tea cosy mystery where the books started and into a bit more heavy mystery-paranormal.

Character growth for both Ophelia and Darci is very well done. Ophelia is beginning to accept her own magical gifts and, through her acceptance, we begin to learn how her magical heritage works as well. Darci is also coming into her own, through Ophelia's mentoring and showing herself to be a clever and intelligent person as well as a beautiful one.

The plot, however, is somewhat muddy. With the addition of so much local color and Tink's plight, their original purpose sometimes gets lost. However, this is still a very well-written and interesting book and a valuable addition to the series.
