Harper believes with a couple of big signings Toon can have an exciting new campaign.
Harper told the Evening Chronicle: "We can have a right go next season. It's the consistency we've got to look for.
"At the start of the season last year, people said it would be our home form that kept us in the division, but we won five games away from home.
"If we can get a few valuable additions, I'm sure we'll be able to turn St James' Park back into a fortress.
"We might get the home wins into double figures, and still pick up the away wins. We could start looking upwards rather than over our shoulders."
