In addition, what I really liked was that Sita is not some kind of wilting wallflower. She is a warrior princess who stands shoulder to shoulder with her husband and brother-in-law, fighting the Rakshshas during their long torturous years in exile. Banker is good with action sequences in particular and manages to make the scenes come alive on paper.
I won't add any more spoilers here for people who haven't read the series. Í'm sure I'll have one more post in store once I am done with Books 5 through 7. Looking forward to yet more hours of reading pleasure!
