for Break Point by Kate Jaimet
It's the summer of Connor Trent's sixteenth birthday, and the stakes for him have never been so high. Connor's summer job at the Bytowne Tennis Club allows him to train at a historic facility. It also throws him into confrontation with his rich-kid rival, Rex Hunter, whom he will battle for a berth in the National Junior Tournament. After a series of fundraisers is sabotaged, Connor suspects that someone wants to bankrupt the club and take over its valuable riverfront property. A fabled trophy, rumored to contain hidden cash, might solve all of Connor's problems, if he can win it.
