When you step into a time machine, fax yourself through a "quantum foam wormhole" and step out in feudal France circa 1357, be very, very afraid. If you aren't strapped back in precisely 37 hours after your visit begins, you'll miss the quantum bus back to 1999 and be stranded in a civil war, caught between crafty abbots, mad lords and peasant bandits all eager to cut your throat. You'll also have to dodge catapults that hurl sizzling pitch over castle battlements. On the social front, you should avoid provoking "the butcher of Crecy" or Sir Oliver may lop your head off with a swoosh of his broadsword or cage and immerse you in "Milady's Bath", a brackish dungeon pit into which live rats are tossed now and then for prisoners to eat. This is the plight of the heroes of Timeline, Michael Crichton's thriller. They're historians in 1999 employed by a tech billionaire-genius with more than a few of Bill Gates' most unlovable quirks. Like the entrepreneur in Crichton's Jurassic Park, Doniger plans a theme park featuring artefacts from a lost world revived via cutting-edge science. When the project's chief historian sends a distress call to 1999 from 1357, the boss man doesn't tell the younger historians the risks they'll face trying to save him. At first, the interplay between eras is clever but Timeline swiftly becomes a swashbuckling old-fashioned adventure, with just a dash of science and time paradox in the mix. Most of the cool facts are about the Middle Ages and Crichton marvellously brings the past to life without ever letting the pulse-pounding action slow down. [+]

Successful novelist Penn Cage comes back to Natchez to recover-a long career as a prosecutor has left him with enemies on both sides of the law and he has been shattered by the death of his wife. A quixotic decision to talk frankly about the town's racial politics to Caitlin, an attractive woman journalist, means he is asked to investigate the long-ago murder of black civil rights worker Del Payton, and almost at once he is being threatened, cajoled and shot at. Cage finds his enquiries coming close to home-his doctor father has skeletons in his closet and Liv Marston, the high school sweetheart Cage loved and lost, comes back into his life the moment he starts investigating the activities and connections of her industrialist father. Iles' Natchez is a superficially civilised rats nest of intrigue where everyone plays the quiet game:White and black both. Everybody keeping quiet, making like things is sweet and easy, trying to fish that new plant in here. Nobody wants nobody digging into Del's killing. Nobody 'cept you. Del's killers is playing the quiet game too. [+]
