THE TEGEN CAVE: From its gut-grabbing prologue to its explosive conclusion, Goss’s spine-tingling debut story gives new meaning to the phrase “a blood-curdling adventure.”—Foreword Clarion Review

After running from her boyfriend’s powerful organized crime family, Sara Jones starts a new life in a new town. But when people around her start dying from poisonous spider bites after she receives a mysterious package with a spider concealed inside, she worries that the family has found her. Life takes an even more bizarre turn when she seems to be not only immune to the spider venom, but also surrounded by a sinister group of people using spiders to incapacitate their prey. Even her new boyfriend starts acting suspiciously. Just who can she trust?
Then to make matters worse Sara’s twenty-fifth birthday approaches, and her dark heritage begins to emerge. She is forced to make a life-or-death decision. And somehow, she must find a way to deal with the crime family.
