Mara Tusconi Oceanography Mystery Series – Charlene D’Avanzo
Updated to post the second in this oceanography mystery series, Demon Spirit, Devil Sea, which is out in May 2017. I had the pleasure of reading an advanced copy of the novel. I wrote:
The novel opens readers’ eyes to a beautiful, mysterious, and threatened rainforest as a climate change crime is investigated by marine biologist Mara Tusconi, who readers will want to see more of in the future. D’Avanzo has written an enchanting tale from an ancient corner of the Earth. Demon Spirit, Devil Sea is a mysterious, fast-paced novel that immerses reader smack dab into the wild.
We are thrilled that our colleague Charlene D’Avanzo’s first climate novel is now published. Charlene has crossed paths with us often, including her selected submission in a short story writing contest that was later published in the anthology Winds of Change: Short Stories about Our Climate, our interview with her as part of the “Women Working in Nature and the Arts” series, and, later, as moderator of our Eco-fiction newsgroup.
Cold Blood, Hot Sea pits climate change scientists against big energy conspirators. When a colleague is killed aboard the research vessel Intrepid, oceanographer Mara Tusconi believes it’s no accident. As she investigates, Mara becomes entangled in a scheme involving powerful energy executives with much to lose if her department colleagues continue their climate change research. Mara’s career—and life—is on the line, threatened by intrigue as big and dark as the ocean.
Marine ecologist and award–winning environmental educator Charlene D’Avanzo studied the New England coast for forty years. As a scientist, D’Avanzo sees firsthand the effects of climate change, and as a college professor, she knows the importance of storytelling in bringing ideas to life. Today she uses mysteries to immerse readers in Maine waters’ stunning beauty and grave threats. An avid sea kayaker, D’Avanzo lives in Yarmouth, Maine. Cold Blood, Hot Sea is her first novel.
The newest novel out in the series is Secrets Haunt the Lobsters’ Sea. See the author’s website for more. The book is scheduled to come out in June 2018.
When a lobsterman’s body is found under Gordy’s aquaculture raft, Mara Tusconi’s cousin Gordy is the number one suspect. But to investigate, Mara must visit Macomek Island, Maine’s wild-wild west where lobstermen practice their own rule of law.
