Kat has just moved to Australia and she has the opportunity to compete at a junior tennis championship in both the singles and doubles categories. She's excited to go but a little worried because she hasn't been there long and doesn't really know anybody yet. She and her roommate Miri, who is also her doubles partner, get off to a bad start when Miri is not home by curfew and asks Kat to lie to their coach for her. Things steadily go downhill, not just for Kat but also for Miri's boyfriend Hamish who is slated to place very well in the competition. Kat senses that Miri may be involved somehow and sets out to figure out what is going on when she is not on the courts herself.
Lots of action and suspense. It's nice to read a sports book that isn't about baseball or football. Also, I like the setting of Melbourne and the comparisons the author (through Kat's voice) makes to the Pacific NW.
