Conclusion of the series. In this book, readers find out what caused the separation between Eoin his blood brothers, Kian and Darach. The three are reunited and resolve the problem that threatens the two worlds. My favorite of the series since readers can really feel the chemistry between Trystyn and Eoin. The banter between the friends was pretty good and Regan just cracked me up with what he said when Trystyn and Eoin were in the Guardian's library letting their fires come together.
