I think these two books be added to the series "Dragons of Solunas", if someone should add them. The series name doesn't appear to be listed anywhere online, however, one of the subtitles of the second book that appears in the paperback copy is "A 'Dragons of Solunas' Novel", so that seems to be the official series name.
