When does a story go from having taken inspiration from another story to having stolen things from it? I ask because someone recently told me that my books "Legends of the Saloli" take too much out of Erin Hunter's "Warriors" series. "Warriors" actually happens to be the story that inspired "Saloli". And yes, when I look back now, I can see a lot of resemblance between the two. Both stories revolve around four tribes of animals living in a forest. One tribe (both of which are named after darkness, no less) wants to take over the forest. An outsider is brought into one of the tribes to help stop the threat. Saloli breaks away a lot, I think, when it really goes into the religious aspects of the story, but I'm afraid people may not make it that far before writing it off as a Warriors rip off. What do you think? Have I overstepped the line between inspiration and thievery?
