The past catches up to Iris Winterbek when she is hunted by a murderous Russian oligarch. All the water-phobic Christmas junkie wants is a traditional White Christmas, but instead she's forced to flee to sunny Florida, where there is no hope of snow.
Holed up on a sailboat, which keeps tilting, making it really hard to decorate the tree, Iris is disgruntled, disoriented, and out of her element. Just as she hatches a plan to lure the villain into a trap, her friends arrive bearing gifts and lead the bad guys straight to her.
As usual, Iris finds herself simultaneously running for cover and hurtling into danger. With lives on the line, Iris must put down the eggnog latte and, once again, launch herself into action hero mode.
