Another welcome addition in the "Ell Donsaii" series, "Habitats" features the return of the favorite freak of genetics in her seventh book, set seven years after the incidents of the first book.
If you're a fan of Ell Donsaii, you'll most likely enjoy this book. It's a return in a number of ways to pre-Tau Ceti Donsaii - there's more focus on Ell and her relationships with friends and colleagues, whereas the Teecees from book six are only obliquely referenced. We also see more action in this book than we have in the previous book, showing a return to the classic Donsaii from the earlier books, with both the skills and the humility that make her an endearing character.
The book isn't without flaws, of course; typical typos occur periodically, and it's hard to keep track of all of the cast of characters that have built up since the first book. To be perfectly blunt, the book suffers the most in the way that all of the Donsaii series does - it's either a dessert or an aperitif, but not a meal unto itself. It's a bit of pleasant distraction, a fluffy treat to indulge in and pull out of the bookshelves when you need a little lift. The science is good, and the questions raised are always intriguing, but it isn't "hard" literature. At the same time, that's perfectly okay.
Personally, I'm thankful for the return to Ell's world and look forward to future visits.
