Maybe Abi can go slow with him and try to prompt him by saying "is this familiar" or "do you remember this"?

I hope they can find a way to be together. I'll be curious how he reacts to her upcoming nuptials.

Maybe if Alex puts his ring on, he'll remember her? The chapter that mentioned them when Abi arrived said he had been wearing them as a necklace.

This is such a great novel. I love that book 3 spilled into Heaven's story.
