The Aeon 14 novels following Tanis Richards[1] have been a consistently good read. The Intrepid Saga and The Orion War series. Haven't ventured into the other offshoots as yet.

The Dome Trilogy[2] was also pretty good, as are the Rho Agenda series[3][4][5].

And if you prefer horror to sci-fi, the I Am Not a Serial Killer series[6] was very good overall, although I thought it lost some steam in the last two books.

And finally, The Rosie Project[7] was so completely charming I ended up reading it straight through in one night.
