Collective Obsessions Saga

By Deborah O'Toole writing as Deidre Dalton


The Collective Obsessions Saga chronicles the extraordinary loves and intricate obsessions between two families sweeping a span of more than 165 years, most of which are set against the backdrop of a Gothic seaside mansion in Maine.


Collective Obsessions Saga by Deborah O'Toole writing as Deidre Dalton


Follow the twists and turns of the Larkin and Sullivan families, who settle in America in the mid-1800s. John Larkin builds his vast business empire while daughter Molly and lighthouse keeper Colm Sullivan establish a connection that will endure for generations.


Amidst murder, madness, perverse self-indulgence and avarice the two families struggle to free themselves from a dark legacy of secrets and obsessions.


Years in the making, Collective Obsessions is a unique family saga set in the combined genres of mystery, paranormal and romance, all dotted with the macabre and hints of classic Gothicism.


The ten-part family saga includes Hearts in Sorrow, The Advent, Quixotic Crossings, The Twain Shall Meet, Enthrallment, The Keeper's Journal, Hearts Desires, The Twilight and Megan's Legacy. The final book in the saga, Limb of Iniquity, is tentatively scheduled for release in 2025.
