Hi has anyone come across this manga called "With the Light: Raising an Autistic Child" a.k.a "Hikari to Tomo ni" ?

I read its recommendation online and wish to read the series, but am not finding it anywhere

Yen Press has released all its volumes, but before purchasing the volumes I would like to see if it's good enough...
