Florian and Margaret are back and this time they have to save Marcus. Marcus's first case is tied to a current case and someone is setting him up to take the fall. Florian and Margaret have to use TOAST to find out which one of their suspects is the culprit. Their investigations take them through the library world of Washington, DC and leave them trapped in the Library of Congress.
This was another fantastic TOAST mystery by James Ponti. I thought this would be the end of the series since it does wrap things up, but Ponti himself has assured me that it will continue. We just had him at the library and he was amazing! Several things in this book made me really happy. I love how attached Florian and Margaret are to Marcus and the family they have formed. I loved that Florian's mom got in on the action and was fantastic. And I loved that Margaret's parentage was dealt with. I do hope there are more books to come.
