A couple of weeks ago, I read "Birthright" (I think it's fairly new in paperback but had been out in hardcover). It's more of a Robb than a Roberts, romance-y but not too much and with more action than the usual. It was one of the better Roberts books I've read in recent years - I had an inkling of who the bad guy was when they were introduced into the storyline, but there were enough twists and turns that I'd forgotten about them and was a bit surprised by the way it ended.
After flying through the last "Death" book like it was candy, I'm wondering where Robb is going to take the series to keep it fresh (because as much as I adore it, it's getting stale). Eve needs to make Captain (I know it'd be fast in terms of real timeline, but in terms of bookline, it's time) and there needs to be some strong new understory with Roarke, who's starting to resemble Galahad (as in predictable scenery instead of character). New characters added in would be good, maybe a bigger role for Trueheart?
