Book suggestions: Grace Rediscovered & Grace-Side Up

This subforum seems much too quiet... are all relevant Methodist and Wesleyan resources already available in Logos? I don't think so, but then I'm not a Methodist...

Currently I'm reading Andrew Sieborger (or Siebörger - a South African pastor I admit having never heard of before) on my Kindle Fire. Very well written stuff.

I want to suggest Grace Rediscovered and Grace-Side Up for either Logos or Vyrso (they would work in Vyrso, I think - not very academic, no big hassle with overboarding footnotes etc).
