Double Crossed: A Spies and Thieves Story is a novella and is a crossover of the Gallagher Girls series and the Heist Society series by Ally Carter.

Macey McHenry meets W. W Hale V at a charity ball when a gunmen crash the party looking for a priceless necklace.

Macey and Hale are so awesome together! I don't ship them, but they do complement each other. I love the Macery mentions Cammie, Bex, and Liz. I love how Macey and Hale acted toward each other, it's kind of hilarious.

Kat and Abby are amazing. I like how Kat and Macey became friends.

I love how the cops just found the gunmen tide up and had no idea how they got there.

I love this novella so much!  Please make a new GG/HS crossover, Ally Carter!!!
