The Clockwork Conspiracy

Issac Turner's dad, Diggory Turner, is the horologist in charge of the Great Clock in the Palace of Westminster. Twice a year, when the clocks change, Diggory climbs Big Ben’s tower to reset the hands of the famous London timepiece. But one day Diggory vanishes from the belfry on the night the clocks go back, leaving behind only a smashed pocket watch and a cryptic message. Isaac, determined to find his father, launches his own investigation with the help of his new friend, headstrong girl called Hattie. However, the pair quickly find themselves hunting down a trail of clues through London's famous landmarks, all while a sinister plot in the gears of government threatens to complicate everything. Issac and Hattie will need to embark on a race against time to save Issac's father - and time itself.
