I've not read any of Higson's Young James Bond series, but picked it up on a 3-for-2 offer on friday, and devoured it over the weekend.
Cor, that was *enormous* fun. Bond arrives at Eton, is bullied, stuff happens, and he ends up in Scotland investigating the mysterious Loch Silverfin, and the Evil Lord Randolph Hellebore, who does Evil things, in an Evil fashion.
Hijinks ensue. There is an Aston Martin.
I'll definitely be investigating the rest of the series.
