Spanning much of the eighteenth and nineteenth centuries, the novel follows the fortunes of the extraordinary Whittaker family as led by the enterprising Henry Whittaker—a poor-born Englishman who makes a great fortune in the South American quinine trade, eventually becoming the richest man in Philadelphia. Born in 1800, Henry's brilliant daughter, Alma (who inherits both her father's money and his mind), ultimately becomes a botanist of considerable gifts herself. As Alma's research takes her deeper into the mysteries of evolution, she falls in love with a man named Ambrose Pike who makes incomparable paintings of orchids and who draws her in the exact opposite direction — into the realm of the spiritual, the divine, and the magical. Alma is a clear-minded scientist; Ambrose a utopian artist — but what unites this unlikely couple is a desperate need to understand the workings of this world and the mechanisms behind all life.Exquisitely researched and told at a galloping pace, The Signature of All Things soars across the globe—from London to Peru to Philadelphia to Tahiti to Amsterdam, and beyond. Along the way, the story is peopled with unforgettable characters: missionaries, abolitionists, adventurers, astronomers, sea captains, geniuses, and the quite mad. But most memorable of all, it is the story of Alma Whittaker, who — born in the Age of Enlightenment, but living well into the Industrial Revolution — bears witness to that extraordinary moment in human history when all the old assumptions about science, religion, commerce, and class were exploding into dangerous new ideas. Written in the bold, questing spirit of that singular time, Gilbert's wise, deep, and spellbinding tale is certain to capture the hearts and minds of readers.

    Gary, driven by thirty years of diverted plans, and Irene, haunted by a tragedy in her past, are trying to rebuild their life together. Following the outline of Gary's old dream, they're hauling logs to Caribou Island in good weather and in terrible storms, in sickness and in health, to build the kind of cabin that drew them to Alaska in the first place. But this island is not right for Irene. They are building without plans or advice, and when winter comes early, the overwhelming isolation of the prehistoric wilderness threatens their bond to the core. Caught in the emotional maelstrom is their adult daughter, Rhoda, who is wrestling with the hopes and disappointments of her own life. Devoted to her parents, she watches helplessly as they drift further apart. Brilliantly drawn and fiercely honest, Caribou Island captures the drama and pathos of a husband and wife whose bitter love, failed dreams, and tragic past push them to the edge of destruction. A portrait of desolation, violence, and the darkness of the soul, it is an explosive and unforgettable novel from a writer of limitless possibility.
