Jaq Silver is back with a bang in this high-octane third novel in the series When Jaq Silver's mother dies, she is handed a poisoned chalice. An inheritance more valuable to her than she could have imagined. Travelling from Portugal to Brazil amid conspiracies and corruption to get to the bottom of her family mystery, Jaq learns she is not the only one with an interest in her unusual inheritance. Racing against the clock as the threats to her life increase on all sides, Jaq must use her scientific know-how to save what matters most. "Fast-paced, roller-coaster ride... The action-packed storyline, just the right side of bonkers, roams from Lisbon to England to the steamy depths of the Brazilian jungle as Erskine lets her imagination rip to great effect."
