Astrid Scholte also wrote Four Dead Queens, a novel with plot twists and strange science fiction technology. This follows the same pattern (though perhaps with less plot twists). After you die, a company can bring you back to life for 24 hours (provided your loved ones pay them lots of money). Tempe wants to bring her sister back for one reason, she knows the secret of their parents' deaths. But that secret leads them down a path of discovering, friendship, and love. There is also Lor, who works for the necromatic company, who is a block of wood, in my opinion.
