I tend to agree with Flamestrike. A video on youtube might be helpful to watch: Top 5 Dungeons and Dragons 5e Rules Everyone Gets Wrong
As for RAW, there is no surprise round in 5e. Surprise is like a condition on a PC or monster which simply means you don't act on your initiative. At times...
One that caught my eye is The Great Dale Campaign Guide
From Joe Raso, Alex Clippinger, Anne Gregersen, Derek Nekritz, Elise Cretel, Emily Smith, Glenn Magas, Oliver Clegg, R P Davis, Scott Bean
I have no affiliation...just think it's cool.
This is such a good time for D&D (5e). There have been times in D&D's history when I was worried the game would fade into oblivion. Not so now days. I'm seeing great products, a great team at Wotc, and an enthusiastic player base. Yep, I'm one of the target audience.
