Bro Strider

Bro Strider is a novelist who writes under two pennames: Dirk Martin (action packed novels that tend to also be highly satirical of politics and wizarding opinions) and Rosalie Foxglove (apparently formulaic romances... which also have hidden political satire elements). He is the father of Dave Strider and Rose LaLonde and part of the reason the Strider-LaLonde family is so weird (the other three members of the family being the other reasons for this).
