Best book for PACU nurse?

Hello,

I'm a new grad nurse starting in the PACU in July and I'd like to prepare myself as much as possible. I did my last 8 weeks in school in the PACU so I'm familiar with many aspects of the care and patients. However, I would like suggestions of one "go to" book for this area. I've searched past threads and haven't gotten a good feel for the best book for this case.

So, what book couldn't you do without as a new PACU nurse or what book have you found since then that you wish you'd had?

Thanks !
