Heart Of Peca - The Heart of the Citadel, #7

Four Guardians... Three Agendas.And One Secret Will Crush Them All. Jannah and her bondmates, the djinn Titan and an amber-coloured dragon named Topaz, return to Peca, with one mission in mind, to protect the Guardians that have been housed within the sacred temples of Peca for over a thousand years. The Chaac, temple priests who reside within the holiest of structures, are bound to the protection of the Guardians and carry a living secret that they will protect with their lives. When the temples are attacked, one by one the Chaac fall, passing on the sacred knowledge and purpose of the Guardians, to the next Chaac in line.
Jannah, Titan and Topaz's arrival interrupts the capture of the last Guardian but Tima, the Chaac of Temple Corichncha is fatally wounded. With no other choice, Tima passes the knowledge of all four protectors to Jannah, who must now balance the intimate knowledge of future events, with her sworn mission to free Peca. Madrid's hunger for the knowledge of the Chaac, as a means to control the Guardians, is insatiable.
He will not stop hunting for Jannah, or the final Guardian. The time draws near when the Emperor's true plan will be revealed to all the worlds. There are only a few more pieces left to put into play, before Madrid's true objectives are revealed.
