Love SomebodyLove Somebody

Seventeen-year-old overachiever Sam attempts to encourage a love connection between her athletic ex-boyfriend Christian and her academic rival Ros while trying not to fall for Ros herself.
Sam Dickson is a charismatic actress with big plans for her future. Ros Shew is a loner, but one of the smartest people in school. Christian Powell is the darling of the high school soccer team, but isn't good at connecting with people. He and Sam broke up after dating for six months, but he makes up for it by being genuine, effusive, and kind, which is why they're still best friends. When Christian falls for Ros on first sight, their first interaction is a disaster, so he enlists Sam's help to get through to her. Sam, with motives of her own, agrees to coach Christian from the sidelines. As Sam starts to realize the complexity of her own feelings, their fragile relationships threaten to fall apart. -- adapted from Goodreads info
