X Marks the Spot by M. J. O'Shea

Jack is trying to keep his TV show on the air and his job.  Alo  just wants to be academic, write his paper and keep his head above water through graduate school.  Alo is gifted his great grandfather's papers and there has always been talk of treasures left behind during World War 2.  Alo does not really want to get involved, but as he looks further into things he can't help himself.  Through a series of events he ends up with Jack and they travel the world, they also hook up.  There are many twists and turns along the way and it was enjoyable and not all of it predictable.
