The Drowning Lesson

Emma and Adam are doctors at the top of their fields and so when they are offered the chance to take their three children to Africa for a year for a research placement it seems like the opportunity of a lifetime. It's going to be an experience they'll never forget.
But for all the wrong reasons.
When Emma arrives home one night to the sickening sight of an empty cot, their family's dream adventure turns into their worst nightmare.
Thousands of miles from home and from anyone who can help, they must discover the truth. Is this a random abduction, a tragic accident or something far more sinister?
