For a couple of weeks now, and probably until the end of the year I've been going through what I call "the bargain bin" of my online bookshop. (everything must be under 5EUR)
There were some really good surprises, mainly S.J. Morden's Frank Kittridge novels and "The Flight of the Aphrodite". They both started in a worrying fashion veering very close to "The Martian" and maybe "Europa Report", but they develop into their own stories with decent characters and (mostly) reasonable actions. The science didn't require me to engage my disbelief suspension field too much, and the endings were quite satisfying.
Frankly I'm surprised that I haven't stumbled upon these books until now, or that he's not better represented as an author in the usual SciFi reading lists.
