Book 4 in Rosemary's saga.

When finally free and tracking down the organisation who made her suffer, in this the fourth book in Rosemary's saga, she is snatched in America and taken to a jungle slave camp.

Here's a taster...

Fire erupted in her sensitive flesh. Snorting through the gag, she tried to absorb the line of agony. Her spread feet momentarily jerked up, leaving her swinging by her wrists until her scrabbling toes again managed to support her weight. Sinews stood out on her throat as she threw her head back in pain. Chest heaving, she blinked sweat from her eyes as Carl’s arm was again raised, this time above her other breast. She felt unable to take another stroke. Already, one breast throbbed in raw agony as if rapidly expanding and contracting whilst tightly bound in red hot barbed wire. Such was her pain that she almost wished that they would cut it off.
