Note: I got this for free.  Principles fall in love, marry, have tragedy, split, get back together (YEARS) later through somewhat unbelievable happenstance.  Some of the medical stuff isn't believable to those of us in the field, but it's a light (reading) romance - so what the hey.  Plenty of angst while the two try to figure out how they feel about each other and where to go from here.
