Realm of Darkness — C.F. Dunn

'“What's it worth, Emma? What are you willing to give in exchange?” 
He brought the journal within tantalising reach and, with each breath, I inhaled its age like incense, its secrets bitter-sweet and lethal.'

In the fourth book of The Secret Of The Journal series, historian Emma D'Eresby has done everything she can to put the past behind her. Now she has every reason to look forward to a future with Dr. Matthew Lynes and his family in the beautiful state of Maine. But, in making peace with her past, she has to face uncomfortable truths in the present. As a shadow from her undergraduate days in Cambridge threatens her happiness, history catches up with terrifying results.

'Captivating and compelling.' Liz Fenwick, author of The Cornish House
