To start off this is the second book in a triliogy set in the Forgotten Realms by Thomas M. Reid called The Scions of Arrabar. The Scions I am guessing are those that are 'heirs' or something of the sort.. and Arrabar is the city they are in.
To tell the true, I can't really remmeber much of the first one because I read it a while back, but this on picked up alright and got me on track about page 60. Vambran his sister Emriana thier aunt Xaphira and Uncle .. as well as the rest of the Matrell family were thrown into turmoil in the first book and the family now ( in this book ) have threats from inside planning to take over the estates. Every family member is at risk and it does not look like any are to make it through.
Also, we are introduced to the Druids and thier leader. Thier cause is to take out all those that would harm the forest, but Vambran has other plans for himself then them killing him. The final take in the book is against the entire city of Arrabar and may take the entire world if nothing is done about it.. but that must be found out in the next book, The Emerald Scepter.
If you enjoy deception and misdirection with family ties then you will enjoy this series.. I have yet to find what the "whole scope" of these books are, but hopefully that will be answered in the final. A die hard fantasy fan, that has read a few Forgotten Realms books will enjoy this, and its not too hard to pick up if not although it is easier.
