Games Series by Jessica Clare (Books 2 & 4)

2. Playing Games
Katy Short doesn't want to be on The World Races. She’s not a social butterfly like her brother (and partner) Brodie. In fact, she’s just as happy to end up in last place as in first.
But when her brother makes a selfish move that pairs her up with silent and surly rock star Liam Brogan, everything in the race changes. Now Katy’s fighting to stay out of the Loser Lodge, just so she won’t have to suffer through all that alone time with Mr. Tall, Dark and Arrogant.
Except Liam? Kinda hot. He’s sexy, pierced… and not nearly as surly as she thought. There’s one good thing about a game with partners -- lots of one-on-one time…

4. Bedroom Games
Kandis Thornton isn’t afraid to lie, scheme, and sneak her way to the grand prize money on the Reality TV show, House Guests. That prize money is the only thing keeping her mother from losing her house (and thus moving in with Kandis). She needs that money, and if she has to step on a few people to do so? She’ll do it. House Guests is a show all about outplaying your house-mates, after all, and she’s not there to make friends.
But Kandis didn’t count on the fact that someone else was going to be playing just as hard as her. And she didn’t plan on teaming up with her nemesis, or scheming their way to the top.
Nor did she plan on sleeping with him.
But these things just happen when you’re stuck in a ridiculous house with nothing but time on your hands and a hot guy sharing your bedroom…
