You need to wait.
The fare should eventually come down to somewhere below £20, rather than the full fare £58.20 it is now.
There is no rush what so ever to purchase tickets. The trains can not sell out, and there are always last minute (even on the day) fares cheaper than what is on offer now. On the day you will never pay the fare on offer now.
The fact that only full fare tickets are on sale means that you won't get a seat reservation anyway now- I have just done several sample bookings to confirm that point.
Very often engineering work happens at weekends, and currently parts of the transpennine route are being electrified, resulting in line closures. When that happens trains are re-routed and sometimes replaced with buses. Currently for instance no trains at all are able to run from Manchester Piccadilly to Leeds, being replaced by bus to Huddersfield. They are all running from Manchester Victoria instead.
Such work is rarely being announced 12 weeks early (whatever other sources say), generally it is around 6 to 8 weeks, sometimes as little as 2 or 3 weeks.
You will get there. Very few people who live in the UK would book a journey such as this so far ahead.
Contrary to what Stroudy says via Liverpool is often the cheapest route (going to Liverpool on Merseyrail) and is not "in the opposite direction".
