Alice Again by Judi Curtin
It's spring mid-term, and Alice has invited Megan to visit her in Dublin. Megan is hoping for a nice trouble-free few days with her best friend. No such luck! She soon discovers that Alice is once again plotting and scheming. It seems that Alice's Mum Veronica has a new boyfriend. The plan is to discover who he is, and to get rid of him. Alice (with poor Megan in tow) becomes totally horrible in an effort to scare the poor man away.
Can this possibly work? Just how horrible can she be? And how can Megan stand by and watch while her best friend turns into a total monster?
