Pink Haired Triplets
Calliden (Cal) is diagnosed with cancer when she is 15. Luckily she's got two brothers that always have her back and know how to make her laugh. They're triplets, and closer than anything, and even cancer can't change that.
Cal's not too sure if she likes how cancer is changing her dad, however. He's decided to step up and be a "good parent," a big change from the drunk, home-but-not-really-there type of guy he was just a few hours before she wound up in the hospital. Sure, it sounds great, a dad who's decided to be involved in her life, but Cal would rather just take care of herself.
Then there's Alex, a fellow cancer patient who has a lifetime of practice of feeling sorry for himself, and pities Cal's new predicament as well.
There is also Matt. Matt: a guy who appears out of nowhere are seems to be everything Cal has ever dreamed of.
