4/5; 4 stars; A-This was an excellent addition to the series. Five books is a long time to wait to start to really connect to the characters in a series but this is the book for me. I was impressed with the Tower, the 'travel', the emerging role of the new leader in Barren. It was all good. I thought it was very well done how Kaylin helped to 'wake' one of the Ancient 'devices' and find a semblance of personhood. Tiamaris has been a stalwart companion, co-worker, and advisor to Kaylin throughout the series and, in this book, he finally finds his place.
