A small plane carrying Cork O'Connor's wife Jo goes missing in Wyoming. After a week-long search, Cork and his son Stephen begin to accept the fact Jo is dead. Six months later, two women approach Cork with evidence that the plane's pilot was an impostor. This gives Cork new hope that Jo's life may not have ended as he assumed, but his new search for answers provokes a trail of murders.
I'm a fan of Krueger's short fiction, but had only read the first Cork book before I was offered Heaven's Keep to review. I remembered Cork and Jo's volatile dynamic from Iron Lake. Part of what tortures Cork and drives his efforts is an unresolved feud with Jo.
Krueger's portrayal of Cork and Stephen's reactions to losing Jo are meaty and genuine. I applaud Krueger and other authors willing to take the creative leap of killing off a major character, injecting a fictional world with realism and resonance.
