Above the Ash. The Coal Elf Chronicles, #3

Whatever the outcome, the North Pole will never be the same. In the final installment of the The Coal Elf Chronicles, Ember Skye Ruprecht has finally had enough. Tired of the constant sparring with the Council and her nemesis-turned-husband, Sturd, Ember demands an audience with the Boss himself: Santa Claus!But first, she will have to contend with a furious Mrs. Claus, who is none too pleased with Ember's decision to undertake the first ever All-Coal Night, where coal is left in the stockings of both the naughty and nice kids all over the world.
Meanwhile, Sturd has gathered up all of the remaining elf twins, promising protection, but Ember and her gang have good reason to doubt the evil elf's intentions.
