I am presently working on a manuscript that has been giving me hell. I know where I’m coming from and where I want to end, but in between are a lot of problems. The main challenge is to fill the time gaps, you know like “this scene is on Sunday and the next important thing happens on Thursday, but what did she do in between? She must have met the guy, she must have done this and that, it’s too boring to tell but how do you take the reader from Sunday to Thursday …?”

This is called a segue and it’s used all the time. The easiest way is to dump everything into a clause: 

“For the next five days, Jane tried to pretend she didn’t care, throwing herself into her work, but on Thursday . . . “

If stuff happens during that time, you may need a full sentence: 

“Jane snapped at her mother on Sunday, savaged a client on Monday, kicked a dog on Tuesday, wept helplessly at work on Wednesday, and then fired her assistant on Thursday when he said, ‘This has to stop.’ Except he was right, so she rehired him and then that afternoon went to see Richard.”  Worst case scenario: It takes an entire paragraph as summary.

The key is to find out if there’s any info in that five days that must be on the page.  If there isn’t, stick with the basics:

“Five days later, Jane . . . “
