Julian Alnwick experienced a tragic childhood, devoid of emotions. However, his life took a significant turn when he encountered his mentors, Dimitri and Ambrosia, who held revered titles among their kind - The King and Queen. Unbeknownst to him, a series of unfortunate events led to Julian being reborn with the mark of the future king, burdening him with new responsibilities, including mastering his insatiable thirst. The idea of having a queen by his side had crossed his mind, but Julian doubted his boyish appearance would attract a suitable partner, despite his exceptional intellect. That is, until an unexpected intervention occurred – a bond known as the mate bond, linking him to a werewolf. The union of a vampire and werewolf seemed like a recipe for complications, raising questions about their compatibility. This story continues the tale from BOOK ONE: "P.S. You're my mate," BOOK TWO: "She's my mate," and BOOK THREE: "I'm his mate," forming the fourth installment in the Mate Series.
