The 19-year-old, who has had recent loan spells at Rochdale and Fleetwood Town, is regarded as one of the brightest defenders in the lower leagues.
"We go back to pre-season training next Wednesday and I am determined to do all I can to impress the manager," Edwards told Sky Sports News.
"The manager knows me having worked with me in the reserves and hopefully that will work in my favour. I have worked hard over the summer and I am ready to hit the ground running when we return for training.
"Hopefully I will get the chance to play a few games in pre-season and show that I deserve a chance in the first team."
Edwards has been linked with a loan move away from the club this summer.
