The Lost Uncle and the elixir of Life

I have illustrated the cover for this book written by Chris Stevens an Isle of Wight author.

When they stumble across a one-hundred-year-old journal detailing the disappearance of their Uncle Cecil, the Baldwin family set off for Sri Lanka in search of the truth.
Had he gone in search of the butterfly flower with its magical healing powers? As the trail goes cold, so fate lends a helping hand, and what they discover is a land beyond their wildest dreams. But when things go horribly wrong, Charlie and Lizzie need to draw on all their courage; the fate of an entire civilisation lies in their hands!
