故事主角是一隻集眾多優點於一身的猴子襪偶Throckmorton S. Monkey，他既可愛、又忠心、還善於聆聽，而且最重要的是從來不會，也不曾忘記微笑。可惜這麼認真的Throckmorton已經被小主人Annaliese遺忘許久，每天只能和其他被動物玩偶共同分享著彼此的寂寞空虛。
A charming sock monkey reunites a fractured family in this simply remarkable novel in the tradition of The Velveteen Rabbit and The Penderwicks.
Meet Throckmorton S. Monkey. He’s everything a sock monkey is supposed to be: Loving. Loyal. A very good listener. And he’s never, ever—not even once!—stopped smiling. Yet Throckmorton has been long forgotten by his keeper Annaliese Easterling, and he seems doomed to live out his days lost and lonely among other abandoned stuffed animals.
But then one day Great Grand Mama Easterling sends engraved invitations to forty-nine sock monkeys to attend her ninetieth birthday along with their human keepers. Throckmorton is thrilled! The arrival of his invitation brings him back together with Annaliese. And he vows to do something so remarkable, so amazing, she will never want to be separated from him again.
Indeed, over just a few days, Throckmorton will survive being buried in a blizzard. He’ll be spared from a vicious attacker. But best of all, he’ll find a way to reunite Annaliese with the one person she most longs to know. Not bad for a stuffed toy—if you’re to believe that’s all Throckmorton S. Monkey really is…
