Seven days to goodbye

After Trina's beloved dog dies, she swears she'll never get another one. But then she learns about service dogs, and realizes that if she becomes a puppy raiser, she could train puppy after puppy and never worry about them dying. But like all great ideas, this one has a serious flaw: her first service puppy must be returned to his kennel at the end of their week-long summer vacation. And saying goodbye to Sydney is going to be much tougher than she ever imagined. Trina's last week with Sydney is made that much harder by her newly strained friendship with her best friend, Sarah, who's become so over-the-top boy crazy that she's almost like a stranger. Sarah is determined to have them hang out with every boy at the beach, but when a boy named Chase takes an interest in Sydney and Trina, it puts an even bigger strain on the friendship. It's hard enough to deal with loosing Sydney, but now she may lose her best friend, too. And even if she manages to patch things up with Sarah--and figures out what to do about Chase--she still must face a daunting decision: is she strong enough to take on another service puppy?
