Three Node Replication (US West, US East and Europe)

Hello! I'm been searching and reading until nearly blind. Your help is appreciated!

We are currently running MySQL in both Master-Slave and Master-Master mode between two continents (North America and Europe). All is well.

We now want to expand another node in the US, so we will have two nodes in the US (East and West Coast) and one in Europe.

We want to be able to read-write at each node using the same application that is running on all three nodes.

I assume this is "three node" Master-Master-Master replication?

However, I cannot find any recommended configuration architectures for more than two Masters? The MySQL presentations say that a "ring" is not recommended, and since a slave can only have one Master, a "hub-spoke" Master-Master seems out of the question.

What are our options?

Thanks!
