I'd do nothing but reading if I could (ok, maybe eat some great food, buy some fancy shoes between two books...oh, and spend some quality time with the gorgeous guy I married while I am on reading-break anyway...)
and the world-building a close second :)
I didn't enjoy the first third, where we got left with two teenagers mostly.
They were pretty boring. Not too bad, considering they were teenagers.
But much less interesting than Mira Delsol. She deserves her own series, without the twins.
She is great.
So, I removed one star for not enough Mira, and too much teenagers.
