It is the first book in The Collegium Chronicles (followed by Intrigues (2010), Changes (2011), Redoubt (2013), and Bastion (2014). It is a depiction of the early history of Valdemar and its timeline is between The Last Herald Mage and Brightly Burning. The book details a change in the training of Heralds from essentially an apprenticeship such as experienced by Tylendel and Vanyel, to a school based system such as the one in Arrows of The Queen and Brightly Burning. Not all Heralds are in favor of this mainly citing lack of supervision as an objection. Source: Wikipedia (en)
