The Archaeology of Minoan Crete
by Reynold Higgins
Amazon for around $5.50 total. There is a short summary of what has been learned through archaeological excavations at each site, but the floorplans and reconstruction views are the real gems. 87 characters in Linear B script are also given with their phonetic values where known, so if you have a d87 time to break it out (scroll to the bottom for the d87 random runes chart). The book also had an interesting but much too short section on the sacred caves of Crete (no maps / surveys there unfortunately). I would just go to Wikipedia for each of the site names listed below for more up to date information than the book can provide, but it is extremely difficult to find quality high-res floorplans let alone isometric restoration views online. Enjoy some scans!
