While that sounds right, I'm with Cyia in wanting to know what they are. Because I don't see anything for 2008-9.
How about looking at who her clients are and then seeing if they've made any sales in the past year?
Laura Langlie's clients: Meg Cabot, Malinda Lo, Jessica Benson, Mignon F. Ballard, Joan Druett, Jack El-Hai, Sarah Elliott, Melanie Lynne Hauser, Robin Hathaway, Mary Hogan, Lauren Lipton, Leslie Margolis, Jonathan Neale, Delia Ray, Cheryl L. Reed, and Jennifer Sturman, + more.
It just requires a bit of research. LL is one of those agents who doesn't have to report her sales anymore. Her reputation kind of speaks for itself, IMO.
