Gall pobl ifanc 12-24 oed hefyd gymryd rhan drwy fenter 'Hac Darllen' Cyngor Llyfrau Cymru. Byddant yn gwirfoddoli mewn llyfrgelloedd i gefnogi Sialens Ddarllen yr Haf.
Young people aged 12-24 can also take part through the Welsh Books Council’s ‘Reading Hack’ initiative which sees them volunteer in libraries to support the Summer Reading Challenge.
