Nat’s class is going on a week-long field trip to hunt for fossils. Cue: mouldy log cabins, potholing, map reading and more totally boring ‘geography stuff’ – all the things that Nat hates… and Dad loves! Of COURSE he volunteers to come along on the trip as a parent helper. Normally Nat would strictly forbid Dad’s attendance BUT he’s finally applied for a ‘proper’ job – teaching survival skills to juvenile delinquents – which will keep him busy and stop him interfering in her life! If all goes well on this trip, he’ll definitely get the job. Nat just needs to keep Dad away from the canoes… and anything involving a zip wire, oh and perhaps they shouldn’t venture up the rather treacherous-looking mountain Bleak Peak during the strongest storm of all time…
