Tess Oliver's Dark Romance Collection is a series of full length sexy adult romance novels set in the nineteenth century and based loosely on horror classics.
Bittersweet Obsession, the first in the series, is based on Mary Shelley's classic, Frankenstein. Angel Van Ostrand has returned from the Peninsular War wounded and dispirited from the horrors of battle only to discover that his father, Dr. Van Ostrand, a once renowned scientist, is engaged in a series of macabre experiments financed by a wealthy baron who seeks immortality. With the melting of winter's frost, Angel is determined to leave his family home, Greystock Manor, forever. But when his father's latest purported triumph over nature comes in the form of an ethereal beauty named Jane, Angel is drawn to her. And now he finds himself in a new battle-- one that involves his heart.
After being stabbed and left for dead in an icy pond, Jane has woken in a strange house under the care of an odd physician and with no recollection of her past. As she recuperates and deals with the slow and painful return of dark memories, she finds that she is losing herself to the doctor's son, Angel. But with each passing day layers of secrets from both the past and present are peeled away and soon Jane discovers that nothing is as it seems.
