Vault is a Madison Kate Novella but is intended to be read after the Hades series as several events overlap and this story DOES contain multiple spoilers for the Hades series. Please consult the recommended reading order for Shadow Grove World on my website if you are uncertain what order to read the books in. This novella is set on a timeline parallel to the events of Club 22 and Timber. Once again. This story WILL spoil the Hades series for you if you haven't read or finished it prior to picking this up.
