This is book four in the excellent Dragon series following up from What a Dragon Should Know
. Its set one year later .I thought nothing could beat the last book, I absolutely love the character Dagmar the Beast, & we continue to see her machinisations & quiet power in action, in this volume. On a personal note I would never have mated her with Gwenvael.Though we do see a different side of him when he tries to protect his siblings from what he sees as unsuitable mates & jealous streak that has hilarious consequences.
You get to meet up with all past characters & from previous books & some new ones, & the adversarial, dysfunctional relationships of the dragons & their mates, political posturing, power game play and the dark plains being attacked by all sides, be it for political gain or physical.
The manipulative bitchy dragon queen Rhainnon orders Northalnd dragon Ragnar to bring Eibhear the Blue home her youngest son to Alwyn the Bloody's twins two year celebration , & bring back her treacherous sister too. But on the way he bumps into princess Keita & her east dragon friend Ren, sparks & insults fly. Wagers are made, tempers are frayed & accusations made.
This series just gets better & better, theres a few threads of romance weaving through, but that is not the main meat of the novel. G.A weaves layers & layers & concentrates on the complex characters & relationships they have with each other, which is very funny, intriguing, with lots of action that flies too soon too the last page. Izzy comes back home too with news of a possible threat, & hoping Eibhear will take notice of her - he does but not the way you think.
Anyway I've blabbed enough, only to say recommended if you like this type of genre, a satisfying read, with lots of loose threads that builds up nicely to the next book.
I suggest though you start with About a Dragon
first & read them in series order.
