A laugh-out-loud tale of love, life lessons, and an odd little man named Mungo Thunk. Bathroom scales were not an appropriate gift for his fiancee's birthday ... apparently. Adam Maxwell isn't a bad man - he's just a man who doesn't stop and think. Ever since he ate seven pickled gherkins for lunch at school, and subsequently shat himself during a maths lesson, Adam has been cursed by a lack of common sense. Now in his early thirties, that lack of common sense is about to throw Adam's life into turmoil after one particularly ill-judged decision backfires ... with disastrous consequences. After a rapid descent towards rock bottom, a strange little man by the name of Mungo Thunk then enters Adam's life. However, not everything about Mungo Thunk is as it first seems. After insisting Adam can rediscover his common sense by agreeing to an unorthodox brand of therapy, the two set about dealing with the raft of challenges Adam has to face. Can Adam trust the mysterious stranger to fix his thinking and get his life back on track? Or will he come to rue the day he invited Mungo Thunk into his life?
