how about in stead of :
"
The task appears straightforward, but the young spy quickly finds herself ensnared in an elaborate trap. Isolated in a hostile country, hunted by the authorities and with her arch-enemy closing in for his revenge, Femke needs all her wit and skills to survive" try putting: "a straight forward task turns into to an elaborate trap as femke finds herself iolated in a hostile country, hunted by the authorities and with a ruthless assassin closing in for his revenge, Femke needs all her wit and skills to survive"
it makes the blurb read more easily whilst keeping the sense of why she is being hunted.
also, could u put a griffon into one of your future books as they are the coolest magical creatures
