How to outline? Glad you asked. You can use index cards. Pleasingly tactile and fun to stack. Use different colors for different plot lines. If you like tools, try Keynote, a small free app that lets you organize notes into outlines.
My personal favorite is yWriter--another free bit of software that makes you pity those who buy software. You can organize by scene or by chapter. You can write inside your outline. Best of all, you can print your outline on...little cards! ( Maybe this is Patterson's secret weapon.)
