Help Finding Elvish phrase

Can anyone help me?


My brother's birthday is next month and I've bought him a copy of 'The Children of Hurin' and would like to inscribe somthing elvish in it for him . Somthing along the lines of 'May you lead a charmed life' or 'may your destiny be blessesd''. Essentially an elvish 'Good luck, God bless' equivalent.
