Storm Born and Thorn Queen are only two other books Richelle Mead wrote. Those are from her adult series Dark
Swan where she has four books out.
But that is not all Richelle wrote for adults, Succubus Heat is the start of another six book Series named Georgina Kincaid.
Which is not a different writing steal just because it is for adults it just goes more in detail for adults.
In this book we see a different Richelle, in this Foretold book she doesn't write by herself she combines her writing steal with different authors to write short stories. Those short stories have some characters from her other books like Vampire Academy. Just to name a few other author who wrote with her on that books are Meg Cabot, Margaret Stohl, Kami Garcia, and many more.
