The Long Utopia - Stephen Baxter, Terry Pratchett

My "OOOOh, Terry Pratchett!" instinct to grab books, led me to grab this one from the library without realizing that it's the fourth in a series, that I haven't read.  Whoops.  Anyone know if the first three are super necessary?  Or if I can read this one without too much destruction?
