I was reading Across the Universe, but then realized I had read it years before and still remembered most of the plot. I then found Synthesis while hunting for DTI, and since I watched the Bynar/Minuet episode just tonight, I decided to read the last novel in the Titan series (not counting Seize the Fire, which I read with the Typhon Pact novels.)
Synthisis is Titan at its best. It was a really cool creative choice to unshackle the AIs from a humanoid form. It is a also shows nice character development for Torvig and Keru from where they started in the series.
