We all come face to face with them, those pesky glitches, oopsies, OMGs and WTFs that ruin a story, turn a reader off, guarantee a slew of one-star reviews—and kill sales.
Beta readers will often point them out. Editors are professional fixers, always on the lookout for booboos. You will realize them yourself when you wake up at 3AM sudden realizing that the MC’s beloved pet who started out as a friendly, tail-wagging Golden Retriever, has somehow become a snarling, saber-toothed attack dog.
These unforced errors range from plot holes, small and economy-size, to lapses in logic. They also include poorly conceived characters, blah settings, pointless dialogue, and momentum-killing info dumps. Even a few will make your book—and you—look like a loser on amateur night.
You need to find them—and fix them—before readers do.
