Once finished with The Sunne in Splendour she claimed to have become "hopelessly hooked" on writing. She had plenty of material to be written about the "rebellious sons and disgruntled brothers and conniving kings and willful queens" of the Plantagenets and hoped to write as many as a dozen books on the subject. After the publication of The Sunne in Splendour, Penman began work on the Welsh Trilogy, set primarily in Wales. The "Welsh Trilogy" was followed by the "Plantagenet series", which presents the events of the life of King Henry II and Eleanor of Aquitaine.
