The story ends with an opening for a new installment. So I can sleep now knowing another adventure is coming. I’ve grown to love their banter even though it is not what it used to be at the beginning. They are older, they know each other better, they’ve experienced things together and went thought hell.
Get it as a standalone or part of the series – an outstanding story and narration as expected. Could be a good gift for a teen to get them into this genre.
