This was the perfect vacation read: light, funny and with a plot that's fairly straightforward.

She's having trouble keeping up with the accounts, mostly because she's not sure how, and then she's accused of embezzling from one of her major clients.
She's living in her brother's basement, and trying to avoid babysitting his toddler daughter Sydney (aka, Princess Banana) who exhibits a curious disdain for her Aunt Izzy, trying to convince herself she doesn't miss her ex-boyfriend Henry, and wondering if her parents' marriage is falling apart.
Salvation comes from where she least expects it (no, I'm not going to tell you), and Izzy and the Agency survive.
Sadly, as the title implies, this is the last of the Spellman Documents. Izzy and her family will be missed.
