Does anyone know about the said three novels of DN Angel?

According to Wikipedia: Three novels were released in Japan between September 2000 and September 2001. The titles are Ningyo no Namida (人魚の涙?, lit. "Mermaid's Tears"), Yuki no Jyoou (雪の女王?, lit. "Snow Queen"), and Garasu no Kutsuri (硝子の靴?, lit. "Glass Shoes"). Although there was an ad for them left in Tokyopop's translation of the fourth manga volume, they have not been licensed, so little is known about them.

I haven't even seen the novels... even the ad. So does anyone know anything else about them and can anyone add some information about them. I couldn't find any information anywhere. Thank you. Griffin-riku 12:52, August 21, 2012 (UTC)Griffin-riku
