The Foundlings and the Fisherman from Tumby chronicles the remarkable and meaningful lives of John and Margaret Treves, a couple beset by daunting challenges and tragedies. Despite their setbacks, the couple contribute whole-heartedly to the needs of the children at the mission and the lepers from the colony. Amidst the duality of light and darkness, land and sea, and the eternal conflict between good and evil, readers are invited to explore the profound meaning of selflessness and sacrifice. The writing is rich in allegory. John Treves's interaction with the tyrannical merqueen is analogous to the wicked, corrupt elements in our world today. The charity of John and Margaret transforms Tumby into a special place where surely they are remembered for their selfless contributions to society as opposed to the merqueen's insatiable thirst for power and wealth.
