Narrative:

We just departed spot X and were cleared to join east and hold short of 27R on east. The intersection was a bit confusing and instead of making the right turn on east, the captain continued on H. We approached 17 and 35 and crossed that runway. Thinking we were on east, we weren't asked to hold short of 17 and 35. After informing ATC of the mistake, we were permitted to continue our taxi to 27R. The remaining flight occurred without further incident.
