As Cass, Lawrie, Cato and Jon head off to du Lac corporate resort Cormorant Atoll for a much-needed break, discord erupts aboard the Claire between the resident members of the Lawrie clan, with Abel's decision regarding his captaincy the pivoting factor. Understandably Abel's crew and staff are caught up in this most onerous decision, since it will mean life-changes for all involved. Lawrie and Jon make a chilling discovery on the island, into the fallout of which Cass and Cato are inevitably pulled, with the realization that both tunnel-troubles and Espiri-influences are considerably more far-reaching than they'd anticipated. And, the repercussions of the discovery follow Cass back to Pilothead Sound in a terrifying way without Lawrie currently present to arbitrate; Cato must fill in for him, though he is facing a dramatic change as well. And Kippie has a most unpleasant surprise for her adoptive uncle Cass, which will affect her standing in the open-minded but propriety-conscious Quad. While Caupoc and company journey deep into the territory of the formidable Don Hidalgo, Ramon continues to struggle for his life, despite Jean-Michelle's constant care and the imparting of a long-kept secret that will bring positive changes to the Deliverer's vast estate in a much-neglected region. Marisco too faces changes, as does Akele; and Caupoc faces a "mishap" at Hidalgo's hands that could well mean the end for him., As does previous volume Nightingale, StormFlight brings about more changes and answers more questions than the previous volumes in the DOPS series, and introduces characters that will be staples in the South American JaVaReyo series, which takes up where the North America-based DOPS leaves off.
