Query: Two Sams At Once

I know this one has been out of print for a while, and it is customary to review newer things or at least things that can be located without a search, but I couldn't stand to see such a fine book supported only by a one star review. This is the only novel where Sam Leaps into two people at once, identical twins. His psyche is split in half, and we get two different versions of Sam: the side that is dedicated to solving the Leap and continuing on to help more people, and the darker more selfish side that is tired of jumping around and wants to settle down and satisfy his own desires. Their two lives unfold and they finally confront each other at the end. I had to leave off the fifth star because this one doesn't reach the emotional depth of several others in the series, the ending is good but not very touching (unlike Angels Unaware, which is perhaps the best in the series).
