Hippolyte's island

In search of a new adventure, Hippolyte Webb, quixotic spirit, modern-day explorer, and natural historian, sets his sights on the Auroras, a group of tiny islands in the middle of the South Atlantic. His destination wouldn't be so unusual, except that these islands were last spotted almost two hundred years ago. Equipped with a centuries-old map, an inadequate sailboat, and an advance payment for a book about his quest, Hippolyte embarks on an unforgettable voyage, not just through unfamiliar seas but through the uncharted territory of his own mind and heart.--from Publisher description (http://www.loc.gov/catdir/enhancements/fy0722/00050839-d.html).
