Nissenson's Wentworth, the son of a Puritan minister, has practically seen it all even before he signs on to occupany Thomas Weston's expedition to Wessagusset in 1622: he's only in his early twenties then, but has already witnessed the (often gruesome) deaths of many of those close to him. And that's before he tries to live through a Massaschusetts winter with a bunch of ill-prepared, ill-provisioned adventurers.
While he's taken some liberties with the Wessagusset story, Nissenson's fictional account certainly could be a worse retelling of the ill-fated colonial endeavor. Wentworth's humanity comes through well in the way he recounts his own history, and I liked how Nissenson put his narrator's "scrivener's habit" of list-making to effective use.
Overall, I liked this well-researched and clearly-written novel.
