This story was told gorgeously through the audiobook! The voices felt authentic to each character (except for Quinn’s, which took some getting used to), and the background music/transition sounds were smooth. Among the plummeting quality of the modern middle grade genre, the writing and story stood out, and by the end, I was attached to the characters and deeply invested in the plot. Side characters and immersive settings (also dolphins) really brought color to everything! The Christian message was very well done — as someone who grew up on Christian fiction, I know how difficult it is to convey without ending up cheesy or dull, but neither came through here. It was woven well throughout the story and integrated into a strong, hopeful backdrop to the adventure. All in all, a good book that I wouldn’t hesitate to recommend to middle grade readers!

Mrs. Sanders, Paul, Ocean and the Dolphin Diamond came alive in this narration, and although the background music during tense conversations was distracting and Quin's voice more cynical than I imagined, I enjoyed listing to Mission Aquamarine. (And the interview at the end entertaining.) Kyle's struggle with God and the stand-off with a Rose agent were very well written for this age group. Good work, Osmond and Mr. Wolfe.
