Lightning by Dean Koontz
Bolts of lightning for us are natural phenomenons forking up in the sky but for Laura Shane it is anything but natural. These lightnings bring tidings, a foreboding or worse, a fate on the brink of death. For each time it strikes somewhere nearby, she knows she'll be in danger and with certainty, she knows her mysterious "guardian angel" will appear to save her. A book of paradoxes is what this is. It lets your mind cruise along its assuming path then flips out on you while your brain scrambles back to get its bearings. Out of all Koontz books, this is an instant favorite even after all these years, even for a non-science junkie like me.
