Greyson Tolliver is a character in the Arc of a Scythe series by Neal Shusterman. He first appears in "The Thunderhead" and later shows importance in "The Toll".
Greyson Chance is a singer. He's 13. He just released his song, Waiting Outside The Lines, on Itunes. He is rumored to be the new Justin Beiber (UGH), but commented that he will not. I really like the name. It reminds me of the singer (duh!) but also it is a character in one of my books. It also reminds me of a boy who is kind of a dreamer, but is very tough. One who has gone through hardship but is still strong.
