Going Tome is actually pretty redundant on the Great Old One, since you're going to want to stay at range due to having no defensive abilities, and the fact that your abilities are focused mostly on non-combat benefits (which is one reason you'd want a lot of cantrips).

But if you're set on Great Old One + Tome, I'd probably go something like this:

Warlock Cantrips: Eldritch Blast, Friends, Mirror Image.
Tome Cantrips: Shocking Grasp, Sacred Flame, Prestidigitation, Guidance

Variant Feat: Resilient: Constitution

Invocations include Book of Ancient Secrets and Mask of Many Faces. Altogether, this would make you a great utility specialist capable of locking down a primary target in combat and maintaining Concentration quite well.
