Something very bad has happened to Alice Toolie. Her secret diary has been read by her worst enemy - Jimmy Cook.

It's war! Until Ms Fennel decides that Alice and Jimmy need to make peace and become pen pals for the term.

And it works. Before long, Alice and Jimmy are planning to make billions of dollars for the school fete - and with a captured ghost and jars full of unicorn vomit, it's sure to be their time to shine.

A laugh-out-loud book filled with sparkle and slime, from the CBCA award-winning writers of the Captain Jimmy Cook Discovers series.
