My daughter [now 15] loved the first book in this series, `Bloodline', which was about the life of the young boy Essa and his battles with the Wolf Clan in Mercia, set during the English Dark Ages [c640 AD]. This book `Bloodline Rising' is the sequel, and it starts off without any of the characters from the first book, as it follows the adventures of Cai, Essa's young son. Known as 'The Ghost', Cai is the fastest and most cunning young criminal in Constantinople. Skilled at lying and deceit, he can twist the minds of men, often bending them to his will. He thinks he is both invisible and invincible. But then fate strikes a blow, and Cai finds himself a slave aboard a ship bound towards Britain - on his way back to the country from which his barbarian parents fled, so long ago. As Cai sharpens his skills of subterfuge and persuasion, war threatens, and he must choose: will he use his phenomenal talents for good, or evil?
These books are aimed squarely at older preteens and teenagers [typically 11+]. My daughter really enjoyed this Bloodline sequel, highly recommending it for the target audience and rating it 4* [a high score for her, where 5* are reserved for `My friend Walter' and `Alone on a wide wide sea']. Like the first Bloodline book this story also comes nicely to a full conclusion, rather than simply ending in a cliff-hanger for the next book in the series. My daughter reads 3 to 5 books a week, and present faves also include The Dresden File series, Nightmare Academy, The Rainbow Opera, The Ask and the Answer, and anything by Michael Morpurgo.
